The GIMPLE store merging pass doesn't merge STRING_CSTs in the general
case, although they are accepted by native_encode_expr; the reason is
that the pass only works with integral modes, i.e. with chunks whose
size is a power of two.
There are two possible ways of extending it to handle STRING_CSTs:
1) lift the condition of integral modes and treat STRING_CSTs as
other _CST nodes but with arbitrary size; 2) implement a specific
and separate handling for STRING_CSTs.
The attached patch implements 2) for the following reasons: on the
one hand, even in Ada where character strings are first-class citizens,
cases where merging STRING_CSTs with other *_CST nodes would be possible
are quite rare in practice; on the other hand, string concatenations
happen more naturally and frequently thanks to the "&" operator, giving
rise to merging opportunities.

PR 96040 revealed IPA-SRA, when checking whether an intended split is
the same as the one in a called function does not also check if the
types match and the transformation code does not handle any resulting
type mismatches. This patch simply avoids the the split in the case
of mismatches, so that we do not have to be careful about invalid
floating-point values being passed in floating point registers and
related issues.

This patch addresses the ICE in gcc.dg/attr-vector_size.c during
make -k check on nvptx-none. The actual ICE looks like:
testsuite/gcc.dg/attr-vector_size.c:29:1: internal compiler error: \
in tree_to_shwi, at tree.c:7321
0xf53bf2 tree_to_shwi(tree_node const*)
../../gcc/gcc/tree.c:7321
0xff1969 nvptx_vector_alignment
../../gcc/gcc/config/nvptx/nvptx.c:5105^M
The problem is that the caller has ensured that TYPE_SIZE(type) is
representable as an unsigned HOST_WIDE_INT, but nvptx_vector_alignment is
accessing it as a signed HOST_WIDE_INT which overflows in pathological
conditions. Amongst those pathological conditions is that a TYPE_SIZE of
zero can sometimes reach this function, prior to an error being emitted.
Making sure the result is not less than the mode's alignment and not greater
than BIGGEST_ALIGNMENT fixes the ICEs, and generates the expected
compile-time error messages.
Tested on --target=nvptx-none, with a "make" and "make check" which results
in four fewer unexpected failures and three more expected passes.

Jakub's partial implementation of consteval virtual had trouble with the
current ABI requirement that we omit the vtable slot for a consteval virtual
function; it's difficult to use the normal code for constant evaluation and
also magically make the slots disappear if the vtables get written out. I
notice that Clang trunk also doesn't implement that requirement, and it
seems unnecessary to me; I expect consteval virtual functions to be
extremely rare, so it should be fine to just give them a vtable slot as
normal but put zero in it if the vtable gets emitted. I've commented as
much to the ABI committee.
One of Jakub's testcases points out that we weren't handling thunks in
our constexpr virtual handling; that is fixed here as well.
Incidentally, being able to use C++11 range-for definitely simplified
clear_consteval_vfns.

The mechanism generating debug info for removed parameters did not
adjust index of the argument in the call statement to take into
account extra arguments IPA-SRA might have produced when splitting a
strucutre. This patch addresses that omission and stops gdb from
showing incorrect value for the removed parameter and says "value
optimized out" instead. The guality testcase will end up as
UNSUPPORTED in the results which is how Richi told me on IRC we deal
with this.
It is possible to generate debug info to actually show the value of
the removed parameter but so far my approaches to do just that seem
toocontroversial
(https://gcc.gnu.org/pipermail/gcc-patches/2020-May/546705.html), so
before I come up with something better I'd like to push this to master
and the gcc-10 branch in time for the GCC 10.2 release.

Bootstrap with musl libc fails with numerous "missing sentinel in
function call" errors. This is because musl defines NULL as 0L for C++,
but gcc requires sentinel value to be a pointer or __null.
Jonathan Wakely says:
To be really safe during stage 1, GCC should not use NULL as a
pointer sentinel in C++ code anyway.
The bootstrap compiler could define it to 0 or 0u, neither of which
is guaranteed to be OK to pass as a varargs sentinel where a null
pointer is expected. Any of (void*)0 or (void*)NULL or nullptr
would be safe.
While it is possible to fix this by replacing NULL sentinels with
nullptrs, such approach would generate backporting conflicts, therefore
simply redefine NULL to nullptr at the end of system.h, where it would
not confuse system headers.

[PR95857]
The following testcase ICEs, because during the cfg cleanup, we see:
switch (i$e_11) <default: <L12> [33.33%], case -3: <lab2> [33.33%], case 0: <L10> [33.33%], case 2: <lab2> [33.33%]>
...
lab2:
__builtin_unreachable ();
where lab2 is FORCED_LABEL. The way it works, we go through the case labels
and when we reach the first one that points to gimple_seq_unreachable*
basic block, we remove the edge (if any) from the switch bb to the bb
containing the label and bbs reachable only through that edge we've just
removed. Once we do that, we must throw away all other cases that use
the same label (or some other labels from the same bb we've removed the edge
to and the bb). To avoid quadratic behavior, this is not done by walking
all remaining cases immediately before removing, but only when processing
them later.
For normal labels this works, fine, if the label is in a deleted bb, it will
have NULL label_to_block and we handle that case, or, if the unreachable bb
has some other edge to it, only the edge will be removed and not the bb,
and again, find_edge will not find the edge and we only remove the case.
And if a label would be to some other block, that other block wouldn't have
been removed earlier because there would be still an edge from the switch
block.
Now, FORCED_LABEL (and I think DECL_NONLOCAL too) break this, because
those labels aren't removed, but instead moved to some surrounding basic
block. So, when we later process those, when their gimple_seq_unreachable*
basic block is removed, label_to_block will return some unrelated block
(in the testcase the switch bb), so we decide to keep the case which doesn't
seem to be unreachable, but we don't really have an edge from the switch
block to the block the label got moved to.
I thought first about punting in gimple_seq_unreachable* on
FORCED_LABEL/DECL_NONLOCAL labels, but that might penalize even code that
doesn't care, so this instead just makes sure that for
FORCED_LABEL/DECL_NONLOCAL labels that are being removed (and thus moved
randomly) we remember in a hash_set the fact that those labels should be
treated as removed for the purpose of the optimization, and later on
handle those labels that way.

In the test case for PR95961, vectorization factor computed
by vect_determine_vectorization_factor is [8,8]. But this is
updated to [1,1] later by vect_update_vf_for_slp. When we call
vect_get_num_vectors in vect_enhance_data_refs_alignment, the number
of scalars which is based on the vectorization factor is not a multiple
of the the number of elements in the vector type. This leads to
the ICE. This isn't a simple stream of contiguous vector accesses.
It's hard to predict from the available information how many vector
accesses we'll actually need per iteration. As discussed, here we
should use the number of scalars instead of the number of vectors as
an upper bound for the loop saving info about DR in the hash table.

A further adjustment of the function cloning. Rather than have
copy_fndecl_with_name deduce whether a particular cdtor needs a
vtt_parm and/or has inherited parms to drop, pass that information in
from the caller. In particular build_cdtor_clones knows when its
building the particular cdtors that might need these. On the modules
branch I need to clone cdtors before the underlying class information
is necessarily complete. There build_cdtor_clones is externally
callable to facilitate that.

This teaches SLP analysis about vector typed externals that are
fed into the SLP operations via lane extracting BIT_FIELD_REFs.
It shows that there's currently no good representation for
vector code on the SLP side so I went a half way and represent
such vector externals uses always using a SLP permutation node
with a single external SLP child which has a non-standard
representation of no scalar defs but only a vector def. That
works best for shielding the rest of the vectorizer from it.
