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.

Some of the i386.exp tests fail on Darwin (and at least one passes
incorrectly on Linux) because their scan-asm match strings are too
general.  In some cases the strings also match instances in the .file
and size directives or in comment output.  This patch makes the match
strings more specific.

A couple of the i386.exp tests fail because the label spelling used
is different between ELF and Mach-O targets. Adjusted here.

	* gcc.target/i386/pr77881.c: Likewise.

From-SVN: r271590

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.

This can't work without special support because placing

PR c++/90462 reports an ICE with -fdiagnostics-format=json when
attempting to serialize a malformed location to JSON.

The compound location_t in question has meaningful "caret" and "start"
locations, but has UNKNOWN_LOCATION for its "finish" location,
leading to a NULL pointer dereference when attempting to build a JSON
string for the filename.

This patch bulletproofs the JSON output so that attempts to write
a JSON object for a location with a NULL file will lead to an object
with no "file" key, and attempts to write a compound location with
UNKNOWN_LOCATION for its start or finish will lead to the corresponding
JSON child object being omitted.

This patch also adds a json::object::get member function, for self-testing
the above.

Here initializing the argument from a TARGET_EXPR isn't an empty class
copy even though the type is !TREE_ADDRESSABLE, so we should check
simple_empty_class_p.

	* call.c (build_call_a): Use simple_empty_class_p.

From-SVN: r271523

Yet another tweak that would have fixed this bug: we should treat INIT_EXPR
and MODIFY_EXPR differently for determining whether this is a simple empty
class copy, since a TARGET_EXPR on the RHS is direct initialization if
INIT_EXPR but copy if MODIFY_EXPR.

	* cp-gimplify.c (simple_empty_class_p): Also true for MODIFY_EXPR.

vect-signbitf.c (dg-final): Improve scan-assembler-not string to avoid false matching on 32bit targets.

	* gcc.target/i386/vect-signbitf.c (dg-final): Improve
	scan-assembler-not string to avoid false matching on 32bit targets.
