Tested that the right -target-cpu is set in the clang -cc1 command line
when running "clang -march=native -E -v - </dev/null" on both an FX-8150
and an FX-8350. Both are family 15h; the FX-8150 (Bulldozer processor)
reports a model number of 1, and the FX-8350 (Piledriver processor)
reports a model number of 2.

Summary:
Add clang-tidy -header-filter option to specify from which headers we
want diagnostics to be printed. By default we don't print diagnostics from
headers. We always print diagnostics from the main file of each translation
unit.

Document and simplify ResolveCondition.

1. Introduce a temporary special case for temporary desctructors when resolving
the branch condition - in an upcoming patch, alexmc will change temporary
destructor conditions to not run through this logic, in which case we can remove
this (marked as FIXME); this currently fixes a crash.

2. Simplify ResolveCondition; while documenting the function, I noticed that it
always returns the last statement - either that statement is the condition
itself (in which case the condition was returned anyway), or the rightmost
leaf is returned; for correctness, the rightmost leaf must be evaluated anyway
(which the CFG does in the last statement), thus we can just return the last
statement in that case, too. Added an assert to verify the invariant.

Performs behind-the-scenes RUN line substitution similarly to what's done with
clang-check and clang-format to ensure the executable is found.

Let's see how far this gets on the build servers. The application requires
native JIT and uses the C standard library, but hopefully we can get this
tested on at least some configurations.

Taking a lead from the clang-format tests, we'll just expect the executable to
get picked up from the build output path for now.

Ideally, importing Foo.a from Foo.b would "do the right thing", but
until it does, this patch makes it an error rather than allow it to
silently be ignored.

This option flag was incorrectly expecting an argument:

$ cindex-dump.py --show-ids test.cpp
cindex-dump.py: error: invalid number arguments

With this change the feature correctly gets enabled by --show-ids.

Windows on ARM does not conform to AEABI.  However, memset would be emitted
using the AEABI signature, resulting in inverted parameters.  Handle this
special case appropriately.

Add handling for FK_SecRel_4 (4-byte section relative relocations).  These are
used by the generation of DWARF debug information (the abbrevations use section
relative relocations).  This will also be used in generation of CodeView line
tables.

Otherwise we use the same threshold as for complete unrolling, which is
way too high. This made us unroll any loop smaller than 150 instructions
by 8 times, but only if someone specified -march=core2 or better,
which happens to be the default on darwin.

When can't assume a vectorized tree is rooted in an instruction. The IRBuilder
could have constant folded it. When we rebuild the build_vector (the series of
InsertElement instructions) use the last original InsertElement instruction. The
vectorized tree root is guaranteed to be before it.

Also, we can't assume that the n-th InsertElement inserts the n-th element into
a vector.

This reverts r207746 which reverted the revert of the revert of r205018 or so.

Fixes the test case in PR19621.

operations on the call graph. This one forms a cycle, and while not as
complex as removing an internal edge from an SCC, it involves
a reasonable amount of work to find all of the nodes newly connected in
a cycle.

Also somewhat alarming is the worst case complexity here: it might have
to walk roughly the entire SCC inverse DAG to insert a single edge. This
is carefully documented in the API (I hope).
