The _mm512_{,mask_}cmp_p[ds]_mask and also _mm_{,mask_}cmp_s[ds]_mask
intrinsics have an argument which must have a constant passed to it
and so use an inline version only for ifdef __OPTIMIZE__ and have
a #define for -O0. But the _mm512_{,mask_}cmp*_p[ds]_mask intrinsics
don't need a constant argument, they are essentially the first
set with the constant added to them implicitly based on the comparison
name, and so there is no #define version for them (correctly).
But their inline versions are defined in between the first and s[ds]
set and so inside of ifdef __OPTIMIZE__, which means that with -O0
they aren't defined at all.
This patch fixes that by moving those after the #ifdef __OPTIMIZE #else
use #define #endif block.

As mentioned in the PR, we generate a useless movzbl insn before lock cmpxchg.
The problem is that the builtin for the char/short cases has the arguments
promoted to int and combine gives up, because the instructions have
MEM_VOLATILE_P arguments and recog in that case doesn't recognize anything
when volatile_ok is false, and nothing afterwards optimizes the
(reg:SI a) = (zero_extend:SI (reg:QI a))
... (subreg:QI (reg:SI a) 0) ...
The following patch fixes it at expansion time, we already have a function
that is meant to undo the promotion, so this just adds the very common case
to that.

convert_like issues errors about bad_p conversions at the beginning
of the function, but in the ck_ref_bind case, it only issues them
after we've called convert_like on the next conversion.
This doesn't work as expected since r10-7096 because when we see
a conversion from/to class type in a template, we return early, thereby
missing the error, and a bad_p conversion goes by undetected. That
made the attached test to compile even though it should not.
I had thought that I could just move the ck_ref_bind/bad_p errors
above to the rest of them, but that regressed diagnostics because
expr then wasn't converted yet by the nested convert_like_real call.
So, for bad_p conversions, do the normal processing, but still return
the IMPLICIT_CONV_EXPR to avoid introducing trees that the template
processing can't handle well. This I achieved by adding a wrapper
function.

The handling of PCH is a little trick, because we have to deal with it before
allocating memory. I found the layering somewhat confusing. This patch
reorganizes that, so that the stopping of PCH is done in exactly one place,

The version of nvprof in CUDA 9.0 causes a hang when used to profile an
OpenACC program. This is because it calls acc_get_device_type from
a callback called during device initialization, which then attempts
to acquire acc_device_lock while it is already taken, resulting in
deadlock. This works around the issue by returning acc_device_none
from acc_get_device_type without attempting to acquire the lock when
initialization has not completed yet.

This breaks building of mesa on both the trunk and 10 branch.
The problem is that the middle-end may never create temporaries of non-POD
(TREE_ADDRESSABLE) types, those can be only created when the language says
so and thus only the FE is allowed to create those.
This patch just reverts the behavior to what we used to do before for the
stores to volatile non-PODs. Perhaps we want to do something else, but
definitely we can't create temporaries of the non-POD type. It is up to
discussions on what should happen in those cases.

This is an ICE-on-invalid but I've been seeing it when reducing
various testcases, so it's more important for me than usually.
splice_late_return_type now checks that if we've seen a late return
type, the function return type was auto. That's a fair assumption
but grokdeclarator/cdk_function wasn't giving errors for function
pointers and similar. So we want to perform various checks not only
when funcdecl_p || inner_declarator == NULL. But only give the
!late_return_type errors when funcdecl_p, to accept e.g.
auto (*fp)() = f;
