Current vectoriser doesn't support masked loads for SLP.
Current vectoriser doesn't support masked loads for SLP. We should add that, to
allow things like:
void
f (int *restrict x, int *restrict y, int *restrict z, int n)
{
for (int i = 0; i < n; i += 2)
{
x[i] = y[i] ? z[i] : 1;
x[i + 1] = y[i + 1] ? z[i + 1] : 2;
}
}
to be vectorized using contiguous loads rather than LD2 and ST2.
This patch was motivated by SVE, but it is completely generic and should apply
to any architecture with masked loads.

[aarch64] Change two function declaration types
Commit r271514 missed changing the type of two functions in
aarch64-protos.h. The function definitions had been updated to use
uint64_t while the function declarations had been missed.
They were missed since I only tested the patch on aarch64 where
`unsigned long` is the same as `uint64_t`.
This patch updates these declarations in aarch64-protos.h.
Tested by building an aarch64 cross-compiler on arm-none-linux-gnu (so
that `unsigned long` and `uint64_t` are different and would give error
messages), and bootstrapping on aarch64-none-linux-gnu.
Also manually tested command line options to see that
-march=armv8-a+typo prints out the expected flags while using the new
feature flags does not complain about missing flags.

Darwin, x86, testsuite - Disable tests that cannot pass.
A few of the i386.exp target tests cannot pass on Darwin
because either the port doesn't support a feature, or the
ABI demands sufficiently different codegen that matching
the output with scan-asms would require a different test.
Disabling those tests here.

One of the static assertions in 20_util/function_objects/invoke/1.cc was
wrong, but didn't fail because by default it was compiled with

From what I understand of the libstdc++/83237 thread at
<https://gcc.gnu.org/ml/gcc-patches/2017-12/msg00573.html>, the
high numbers are not arbitrary, so it seems wrong to try
lowering them, or we'd just waste cycles testing nothing, or
worse, ending up with a bogus error indication. Better to just
plain disable this part of the test for simulator targets; I
assume the results should be the same on any IEEE-float target,
i.e. no target-specific things going on here that'd raise a need
to cover it everywhere.
With this part of the test disabled, I saw the test finishing in
(time) "124.74s user" where it was before "1120.26s user"
running the cris-elf-run simulator on a "i7-4770K CPU @ 3.50GHz"
host. Most certainly that indidates that the remainder of the
test is still too much for *some* host+simulator combos, but I'm
happy with the runtime lowered to 1/5 of the timeout (10
minutes) on this particular combination, and I'd think this
fixes timeouts for many other simulator combos too.
This construct (disabling or lowering limits for simulators) is
used elsewhere in the libstdc++ test-suite and in particular the
SIMULATOR_TEST macro is used in the testsuite machinery (though
AFAICT not in testDiscreteDist).
