PR 86153 was originally filed when changes to the C++11's
implementation of vector resize(size_type) limited inlining that were
required for testsuite/g++.dg/pr83239.C to verify that we did not
issue an undesired warning.

That was worked by increasing the limit for inlining, but that in turn
caused the C++98 implementation of vector resize, that is
significantly different, to also be fully inlined, and that happened
to issue the very warnings the test was meant to verify we did NOT
issue.

The reason we issued the warnings was that we failed to optimize out
some parts of _M_fill_insert, used by the C++98 version of vector
resize, although the call of _M_fill_insert was guarded by a test that
could never pass: test testcase only calls resize when the vector size
is >= 3, to decrement the size by two.  The limitation we hit in VRP
was that the compared values could pass as an overflow test, if the
vector size was 0 or 1 (we knew it wasn't), but even with dynamic
ranges we failed to decide that the test result could be determined at
compile time, even though after the test we introduced ASSERT_EXPRs
that required a condition known to be false from earlier ones.

I pondered turning ASSERT_EXPRs that show impossible conditions into
traps, to enable subsequent instructions to be optimized, but I ended
up finding an earlier spot in which an overflow test that would have
introduced the impossible ASSERT_EXPR can have its result deduced from
earlier known ranges and resolved to the other path.

Although such overflow tests could be uniformly simplified to compares
against a constant, the original code would only perform such
simplifications when the test could be resolved to an equality test
against zero.  I've thus avoided introducing compares against other
constants, and instead added code that will only simplify overflow
tests that weren't simplified before when the condition can be
evaluated at compile time.

When binding an object to a template parameter of reference type, we
take the address of the object and dereference that address.  The type
of the address may still carry (template) typedefs, but
verify_unstripped_args_1 rejects such typedefs other than in the top
level of template arguments.

Canonicalizing the type we want to convert to right after any
substitutions or deductions avoids that issue.

This patch started out from the testcase in PR88146, that attempted to
synthesize an inherited ctor without any args before a varargs
ellipsis and crashed while at that, because of the unguarded
dereferencing of the parm type list, that usually contains a
terminator.  The terminator is not there for varargs functions,
however, and without any other args, we ended up dereferencing a NULL
pointer.  Oops.

Guarding accesses to parm would be easy, but not necessary.  In
do_build_copy_constructor, non-inherited ctors are copy-ctors, that
always have at least one parm, so parm needs not be guarded when we
know the access will only take place when we're dealing with an
inherited ctor.  The only other problematic use was in the cvquals
initializer, a variable only used in a loop over fields, that we
skipped individually in inherited ctors.  I've guarded the cvquals
initialization and the entire loop over fields so they only run for
copy-ctors.

Avoiding the crash from unguarded accesses was easy, but I thought we
should still produce the sorry message we got in other testcases that
passed arguments through the ellipsis in inherited ctors.  I put a
check in, and noticed the inherited ctors were synthesized with the
location assigned to the class name, although they were initially
assigned the location of the using declaration.  I decided the latter
was better, and arranged for the better location to be retained.

Further investigation revealed the lack of a sorry message had to do
with the call being in a non-evaluated context, in this case, a
noexcept expression.  The sorry would be correctly reported in other
contexts, so I rolled back the check I'd added, but retained the
source location improvement.

I was still concerned about issuing sorry messages while instantiating
template ctors even in non-evaluated contexts, e.g., if a template
ctor had a base initializer that used an inherited ctor with enough
arguments that they'd go through an ellipsis.  I wanted to defer the
instantiation of such template ctors, but that would have been wrong
for constexpr template ctors, and already done for non-constexpr ones.
So, I just consolidated multiple test variants into a single testcase
that explores and explains various of the possibilities I thought of.

Backports a fix where a bad cast to TypeFunction resulted in memory
corruption.  The logic in the function semantic has been fixed, and
casts have been replaced with a function call to always check the
front-end AST node value.

dwarf2out_finish performs:

1. save_macinfo_strings
2. hash table traverse of index_string
3. output_macinfo -> output_macinfo_op
4. output_indirect_strings -> hash table traverse of output_index_string

find_slot_with_hash has

 if (insert == INSERT && m_size * 3 <= m_n_elements * 4)
    expand ();

which may expand hash table even if no insertion is neeed and change hash
table traverse order.  When output_macinfo_op is called, all index strings
have been added to hash table by save_macinfo_strings and we shouldn't
expand index string hash table.  Otherwise find_slot_with_hash will expand
hash table when hash table has the right size and hash table traverse of
output_index_string will have a different traverse order from index_string.

	PR debug/79342
	* dwarf2out.c (find_AT_string_in_table): Add insert argument
	defaulting to INSERT and replace INSERT.
	(find_AT_string): Likewise.
	(output_macinfo_op): Pass NO_INSERT to find_AT_string.
