[compiler-rt][libunwind] Support aarch64 without FPU (#111235)
These two libraries don't build for `-march=armv8-a+nofp
-mabi=aapcs-soft` as a couple of uses of floating point instructions and
registers have crept in.
In libunwind, skip save/restore of FPU registers on targets without them.
In compiler-rt, fall back to the old C implementation of __arm_sc_memset when
the target doesn't have an FPU.

[AArch64][SME] Make use of Arm Optimised Routines in compiler-rt (#99326)
A number of streaming-compatible versions of standard C functions
were added to compiler-rt, however there are already optimised
versions of most of these in libc which are valid in streaming-SVE
mode. This patch replaces the implementations of __arm_sc_mem* with
these versions where possible.

[AArch64][compiler-rt] Avoid use of libc header in sme-libc-routines (#79454)
The use of `#include <stdlib.h>` introduces a libc dependency. In many
build environments such a file can be found under e.g. /usr/include, but
this does not necessarily correspond to the libc in use, which may not
be available until after the builtins have been built.
So far as I understand, it's not valid to have a dependency on libc from
builtins; there are a handful of such includes in builtins, but they are
protected by ifdefs.
Instead, use <stddef.h>, which provides `size_t` and is provided by the
compiler's resource headers and so should always be available.
