x86: Don't allocate stack frame nor align stack if not needed
get_frame_size () returns used stack slots during compilation, which
may be optimized out later. This patch does the followings:
1. Add stack_frame_required to machine_function to indicate that the
function needs a stack frame.
2. Change ix86_find_max_used_stack_alignment to set stack_frame_required.
3. Always call ix86_find_max_used_stack_alignment to check if stack
frame is needed.

[aarch64] Introduce flags for SVE2.
This patch adds support in the compiler for the architecture feature
flags that binutils will use to enable/disable the new "Future
Architecture Technologies" feature Scalable Vector Extension V2 (SVE2)
announced at Linaro Connect this week.
The "sve2" extension that enables the core sve2 instructions.
This also enables the sve extension, since sve is a requirement of sve2.
Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.
When introducing macros to denote these new features we have gone past
what a 32 bit value can represent which means we need to change the type
of those variables working with these feature flags to ensure they use
64 bit quantities.
Tested with bootstrap on aarch64-none-linux-gnu and manually seeing that
-march=armv8-a+typo prints out the expected flags while using the new
feature flags does not complain about a missing flag (until reaching the
assembler).

[RS6000] Don't pass -many to the assembler
I'd like to remove -many from the options passed by default to the
assembler, on the grounds that a gcc bug in instruction selection (eg.
emitting a power9 insn for -mcpu=power8) is better found at assembly
time than run time.
For now, just do this when --enable-checking or gcc is not a release.
This patch also emits .machine assembler directives for ELF targets
when functions are compiled for different cpus via attributes or
pragmas. That's necessary when the initial -m<cpu> option passed to
the assembler doesn't enable the superset of all opcodes emitted, as
seen by a failure of gcc.target/powerpc/clone2.c without .machine
when building gcc for power8.
rs6000_machine_from_flags deliberately uses ISA_2_4_MASKS rather than
ISA_2_2_MASKS for power5 because "friz" and other similar instructions
enabled by gcc with TARGET_FPRND are enabled in gas by "-mpower5".
(gas -mpower5 supports power5+ too.) rs6000-cpus.def puts
OPTION_MASK_FPRND in ISA_2_4_MASKS, so ISA_2_4_MASKS is the one to use
in deciding to pass "-mpower5" to gas.
O3-pr70130.c also failed on an earlier version of this patch (when
only testing one ISA bit to determine .machine). This is a test for a
power7 vector bug, but on power8 hw check_vect_support_and_set_flags
passes -mpower8-vector which means the test isn't exercising the
original bug exactly. I reckon that is wrong, and similary for other
vector testcases that ask for a specific cpu. I've fixed it here by
explicitly passing -mno-power8-vector and similar vector options.

preserve more debug stmts in gimple jump threading
Gimple jump threading does not duplicate forwarder blocks that might
be present before or after the second copied block. This silently
drops debug binds and markers that might be present in them. This
patch attempts to preserve them.
For blocks after either copied block, we attempt to append debug stmts
to the copied block, if it does not end with a block-ending stmt.
Failing that, for blocks between both copied blocks, we prepend its
debug stmts to the copy of the second block.
If everything fails, we still drop debug stmts on the floor, though
preexisting code consolidates debug binds in the block that threading
flows into, so only markers are really lost. We can't do much better
than that without conditional binds and markers, or debug stmts in
edges, or somesuch.
If we append debug stmts to a reusable template block, we copy it
after splitting out the debug stmts, and before putting them back.

* tree-ssa-threadupdate.c (struct ssa_local_info_t): Add
field template_last_to_copy.

PR c++/90532 Ensure __is_constructible(T[]) is false
An array of an unknown bound is an incomplete type, so no object of such
a type can be constructed. This means __is_constructible should always
be false for an array of unknown bound.
This patch also changes the std::is_default_constructible trait to use
std::is_constructible, which now gives the right answer for arrays of
unknown bound.
