There are a few places in libgcc assembly where we don't emit call
frame information for functions, potentially breaking unwinding from
asynchronous signal handlers.  This patch fixes them.  Although I
patch tramp.S there is no attempt made to provide CFI for the actual
trampoline on the stack.  Doing that would require generating CFI at
run time and both registering and deregistering it, which is probably
not worth doing since it would significantly slow down the call.

The -mcpu=native support has bit-rotted a little, in particular the
fallback when the native cpu couldn't be determined.  This patch fixes
the bit-rot and reorganizes ASM_CPU_SPEC so that it should be a little
easier to keep the -mcpu=native data up to date.

The patch also changes the fix for PR63177 (-mpower9-vector being
passed by the user when the default is -mpower8) to also apply when
-mcpu=powerpc64le and -mcpu=native is given.  I'll note that the hack
for PR63177 should probably be extended to lots of other options, if
we're going to continue supporting all those sub-architecture options
(-mpower9-vector, -mpower8-vector, -mcrypto, -mdirect-move, -mhtm,
-mvsx and others) in the positive sense.  I think those should have
only been supported in their -mno- variants..

The dump_* API attempts to capture emission location metadata for the
various dump messages, but looking in -fsave-optimization-record shows
that many dump messages are lacking useful impl_location values, instead
having this location within dumpfile.c:

            "impl_location": {
                "file": "../../src/gcc/dumpfile.c",
                "function": "ensure_pending_optinfo",
                "line": 1169
            },

The problem is that the auto-capturing of dump_impl_location_t is tied to
dump_location_t, and this is tied to the dump_*_loc calls.  If a message
comes from a dump_* call without a "_loc" suffix (e.g. dump_printf), the
current code synthesizes the dump_location_t within
dump_context::ensure_pending_optinfo, and thus saves the useless
impl_location seen above.

This patch fixes things by changing the dump_* API so that, rather than
taking a dump_flags_t, they take a new class dump_metadata_t, which is
constructed from a dump_flags_t, but captures the emission location.

Hence e.g.:

  dump_printf (MSG_NOTE, "some message\n");

implicitly builds a dump_metadata_t wrapping the MSG_NOTE and the
emission location.  If there are several dump_printf calls without
a dump_*_loc call, the emission location within the optinfo is that
of the first dump call within it.

The patch updates selftest::test_capture_of_dump_calls to verify
that the impl location of various dump_* calls is captured.  I also
verified things manually.

    Create a framework for putting function bodies in export data.  At
    present only empty functions will be put there, and they will be
    ignored on import.  Later patches will get this to the point of
    supporting inlining of (some) functions defined in other packages.

From-SVN: r266472

The mul64 attribute in types.md causes some confusion as it is used to represent
aarch32 instructions that do widening multiplication to generate 32->64 bit results.
But these types are shared with aarch64, which has native 64-bit multiplication operations.

Those are currently not properly represented, which I will fix in follow-up patches.
For now, this patch renames the mul64 attribute to widen_mul64 to more clearly communicate its meaning.

It mechanically updates all users of that name in config/arm/ (there are no users in config/aarch64).
There is thus no change in behaviour.

	(widen_mul64): ... This.

When throwing an Exception in the Fiber the backtrace generation
crashes.  This happens because backtrace does not func the stack bottom.
Using '.cfi_undefined x30' tells the debug info that the value in the lr
is unknown, which seems to be the nicest way to stop the unwinder.
Setting x30 to 0 is another option, however it still creates one invalid
frame in gdb, so the .cfi variant is used here instead.

Backport from upstream druntime 2.083.
