This makes the control dependence compute avoid a find_edge
and optimizes allocation by embedding the bitmap head into the
vector of control dependences instead of allocating all of them.
It also uses a local bitmap obstack.
The bitmap changes make it necessary to shuffle some includes.

When investigating false positives on the Linux kernel from
-Wanalyzer-use-of-uninitialized-value, I noticed that the existing
implementation of switch statements in the analyzer is broken.
Specifically, the existing implementation assumes a 1:1 association
between CFG out-edges from the basic block and case labels in the
gimple switch statement. This happened to be the case in the
examples I had tested, but there is no such association in general.
In particular, in the motivating example:
arch/x86/kernel/cpu/mtrr/if.c: mtrr_ioctl
the switch statement has 3 blocks, each covering multiple ranges of
ioctl command IDs for which different local variables are initialized,
which the existing implementation gets badly wrong. [1]
This patch reimplements switch handling in the analyzer to eliminate
this false assumption - instead, for each out-edge we gather the set
of case labels for that out-edge, and use that to determine the
set of value ranges for the edge. Avoiding false positives for the
above example requires that we accurately track value ranges for
symbolic values, so the patch extends constraint_manager with a new
bounded_ranges_constraint, adding just enough information to capture the
ranges for switch statements whilst retaining combatility with the
existing constraint-handling (ultimately I'd prefer to simply throw
all of this into a SAT solver and let it track things).
Doing so fixes the false positives seen on the Linux kernel and an
existing xfail in the test suite.
The patch also fixes a long-standing bug in

gimple.h has this comment for gimple's uid field:
/* UID of this statement. This is used by passes that want to
assign IDs to statements. It must be assigned and used by each
pass. By default it should be assumed to contain garbage. */
unsigned uid;
and gimple_set_uid has:
Please note that this UID property is supposed to be undefined at
pass boundaries. This means that a given pass should not assume it
contains any useful value when the pass starts and thus can set it
to any value it sees fit.
which suggests that any pass can use the uid field as an arbitrary
scratch space.
PR analyzer/98599 reports a case where this error occurs in LTO mode:
fatal error: Cgraph edge statement index out of range
on certain inputs with -fanalyzer.
The error occurs in the LTRANS phase after -fanalyzer runs in the
WPA phase. The analyzer pass writes to the uid fields of all stmts.
The error occurs when LTRANS is streaming callgraph edges back in.
The LTO format uses stmt uids to associate call stmts with callgraph
edges between WPA and LTRANS.
For example, in lto-cgraph.c, lto_output_edge writes out the
gimple_uid, and input_edge reads it back in.
lto_prepare_function_for_streaming has code to renumber the stmt UIDs
when the code is streamed back out, but for some reason this isn't
called for clones:
307 /* Do body modifications needed for streaming before we fork out
308 worker processes. */
309 FOR_EACH_FUNCTION_WITH_GIMPLE_BODY (node)
310 if (!node->clone_of && gimple_has_body_p (node->decl))
311 lto_prepare_function_for_streaming (node);
Hence the combination of -fanalyzer and -flto will fail in LTRANS's
stream-in if any function clones are encountered.
It's not fully clear to me why this isn't done for clones, and what the
correct fix should be to allow arbitrary changes to uids within WPA
passes.
In the meantime, this patch works around the issue by updating the
analyzer to save and restore the UIDs, fixing the error.

This patch and the followup eliminate various forms of non-determinism
in the analyzer due to changing pointer values.
This patch fixes churn seen when diffing analyzer logs. The patch
avoids embedding pointers in various places, and adds sorting when
dumping hash_set and hash_map for various analyzer types. Doing so
requires implementing a way to sort svalue instances, and assigning UIDs
to gimple statements.
Tested both patches together via a script that runs a testcase 100 times,
and then using diff and md5sum to verify that the results are consistent
in the face of address space randomization:

This patch extends -fdump-analyzer-supergraph so that rather than just
dumping a DUMP_BASE_NAME.supergraph.dot at the start of analysis, it
also dumps a DUMP_BASE_NAME.supergraph-eg.dot at the end.
The new dump file contains a concise dump of the exploded_graph,
organized with respect to the supergraph and its statements. The
exploded nodes are colorized to show sm-state, but no other state
is shown. Per exploded_node saved_diagnostics are also shown,
along with feasibility of the paths to reach them.
I've been finding this a useful way of tracking down issues in
exploded_graphs that are sufficiently large that the output of
-fdump-analyzer-exploded-graph becomes unwieldy.
The patch extends feasiblity-testing so that if the exploded_path
for a saved_diagnostic is found to be infeasible, the reason is
saved and written into the saved_diagnostic, so it can be shown in the
dump. I've found this very useful when tracking down feasibility
issues.
I'm keeping the initial dump file as it's useful when tracking down
ICEs within the analyzer (which would stop the second dump file being
written).

This patch adds various information to -fdump-analyzer and
-fdump-analyzer-stderr to make it easier to track down
problems with state explosions in the exploded_graph.
It logs the number of unprocessed nodes in the worklist, for
the case where the upper limit on exploded nodes is reached.
It prints:
[a] a bar chart showing the number of exploded nodes by function, and
[b] bar charts for each function showing the number of exploded nodes
per supernode/BB, and
[c] bar charts for each function showing the number of excess exploded
nodes per supernode/BB beyond the limit
(--param=analyzer-max-enodes-per-program-point), where that limit
was reached
I've found these helpful in finding exactly where we fail to consolidate
state, leading to state explosions and false negatives due to the
thresholds being reached.
The patch also adds a "superedge::dump" member function I found myself
needing.

PR analyzer/93288 reports an ICE in a C++ testcase when calling a
constructor.
The issue is that when building the supergraph, we encounter the
cgraph edge to "__ct_comp ", the DECL_COMPLETE_CONSTRUCTOR_P, and
this node's DECL_STRUCT_FUNCTION has a NULL CFG, which the analyzer
reads through, leading to the ICE.
This patch reworks function and fndecl lookup at calls throughout the
analyzer so that it looks for the ultimate_alias_target of the callee.
In the case above, this means using the "__ct_base " for the ctor,
which has a CFG, fixing the ICE.
Getting this right allows for some simple C++ cases involving ctors to
work, so the patch also adds some test coverage for that.

PR analyzer/93375 reports an ICE under certain circumstances
involving a call where the number of arguments at the callsite
is less than the parameter count of the callee,
Specifically, the ICE occurs when pruning a checker_path for a
diagnostic, when attempting to maintain which expression is of
interest through such a call.
The root cause is an assumption that there were enough arguments at
the callsite, within callgraph_superedge's methods for mapping
expressions between callee and caller.
This patch adds checks for this to the relevant methods, fixing the ICE.

PR analyzer/93307 reports that in an LTO bootstrap, there are ODR
violations between:
- the "region" type:
gcc/analyzer/region-model.h:792
vs:
gcc/sched-int.h:1443
- the "constraint" type:
gcc/analyzer/constraint-manager.h:121
vs:
gcc/tree-ssa-structalias.c:533
This patches solves this clash by putting all of the analyzer names
within a namespace. I chose "ana" as it is short (to save typing).
The analyzer selftests are moved from namespace "selftest" to
"ana::selftest".
There are various places where the namespace has to be closed
and reopened, to allow e.g. for specializations of templates
in the global namespace.

In the reproducer for PR analyzer/58237 I noticed that some events were
missing locations (and text); for example event 3 here:
| 15 | while (fgets(buf, 10, fp) != NULL)
| | ~
| | |
| | (2) following 'false' branch...
|
'f1': event 3
|
|cc1:
|
'f1': event 4
|
|<source>:19:1:
| 19 | }
| | ^
| | |
| | (4) 'fp' leaks here; was opened at (1)
|
The root cause is that various places in the analyzer compare locations
against UNKNOWN_LOCATION, which fails to detect an unknown location for
the case where an unknown_location has been wrapped into an ad-hoc
location to record a block.
This patch fixes the issue by using get_pure_location whenever testing
against UNKNOWN_LOCATION to look through ad-hoc wrappers.
For the case above, it thus picks a better location in
supernode::get_start_location for event (3) above, improving it to:
| 15 | while (fgets(buf, 10, fp) != NULL)
| | ~
| | |
| | (2) following 'false' branch...
|......
