[AArch64] Support zero-extended move to FP register
The popcount expansion uses SIMD instructions acting on 64-bit values.
As a result a popcount of a 32-bit integer requires zero-extension before
moving the zero-extended value into an FP register. This patch adds
support for zero-extended int->FP moves to avoid the redundant uxtw.
Similarly, add support for 32-bit zero-extending load->FP register
and 32-bit zero-extending FP->FP and FP->int moves.
Add a missing 'fp' arch attribute to the related 8/16-bit pattern and
fix an incorrect type attribute.
To complete zero-extended load support, add a new alternative to
load_pair_zero_extendsidi2_aarch64 to support LDP into FP registers too.

Make ext allocators support heterogeneous equality comparison
The Allocator requirements include the ability to compare different

for __gnu_cxx::new_allocator and other extension allocators. This patch
replaces the equality operators for those allocators with inline friends
that support heterogeneous comparisons. (I'm not changing all ext
allocators because some are bit-rotted already).
Additionally, the equality operators for comparing two std::allocator
objects of the same type are now defined as inline friends. Those
overloads don't need to be declared at namespace scope, because they
aren't specified in the standard (but they're needed in this
implementation to avoid ambiguities caused by the extra overloads

malloc_allocator max_size() members to use PTRDIFF_MAX instead of
SIZE_MAX (and because they define it, the allocator_traits default isn't

This is part 2/2 for contributing PPC64LE support for X86 SSE3
instrisics. This patch includes testsuite/gcc.target tests for the
intrinsics defined in pmmintrin.h.
Tested on POWER8 ppc64le and ppc64 (-m64 and -m32, the latter only reporting
10 new unsupported tests.)

This is a follow-on to earlier commits for adding compatibility
implementations of x86 intrinsics for PPC64LE. This is the first of
two patches. This patch adds 11 of the 13 x86 intrinsics from
<pmmintrin.h> ("SSE3"). (Patch 2/2 adds tests for these intrinsics,
and briefly describes the tests performed.)
Implementations are relatively straightforward, with occasional
extra effort for vector element ordering.
Not implemented are _mm_wait and _mm_monitor, as there are no
direct or trivial analogs in the POWER ISA.

runtime: skip testSetPanicOnFault for gollvm
LLVM doesn't support non-call exception. This test was passing
more or less by luck: if the faulting instruction is between two
calls with the same landing pad (in instruction layout order,
not the program's logic order), it generates a merged PC range
that covers the faulting instruction. If the instruction layout
order changes, or it uses two different (but may be degenerate)
landing pads, this doesn't work.

[Ada] Fix spurious -Wuninitialized warnings for small records
This change is aimed at getting rid of spurious -Wuninitialized warnings
issued for small records passed by copy and containing default values
for some of their components.
The source of the problem is that the _Init parameter of the
initialization routine is declared as an in/out parameter, so the
uninitialized object is passed by copy to it and this can be flagged by
-Wuninitialized.
That's why the mode of the parameter is changed to out, except for the
cases where information really needs to be passed in: unconstrained
array types, protected and task types.
For the following record type Rec!
type Rec is record
B : Boolean := True;
end record;
the initialization routine must now be:
procedure r__recIP (_init : out r__rec1) is
begin
_init.b := true;
return;
end r__recIP;

[Ada] Ignore pragmas Compile_Time_Error/Warning in GNATprove mode
GNATprove does not have sometimes the precise information of the
compiler about size of types and objects, so that it cannot evaluate the
expressions in pragma Compile_Time_Error/Warning the same way the
compiler does. Thus, these pragmas should be ignored in GNATprove mode,
as it can neither verify them nor assume them (if the expression cannot
be evaluated at compile time, then the semantics for GNAT is to ignore
them).

[Ada] Fix spurious error on derived record passed as Out parameter
This fixlet gets rid of a spurious error issued in the specific case of
a call to a subprogram taking an Out parameter of a discriminated record
type without default discriminants, if the actual parameter is the
result of the conversion to the record type of a variable whose type is
derived from the record and has a representation clause.
The compiler was failing to initialize the temporary made around the
call because of the representation clause, but this is required for a
type with discriminants because discriminants may be read by the called
subprogram.
