Szabolcs Nagy efbe665c3a [AArch64] Fix libc internal asm profiling code 
When glibc is built with --enable-profile, the ENTRY of
asm functions includes CALL_MCOUNT for profiling.
(matters for binaries static linked against libc_p.a.)

CALL_MCOUNT did not save/restore argument registers
around the _mcount call so it clobbered them.
(it is enough to only save/restore the arguments passed
to a given asm function, but that would be too many asm
changes so it is simpler to always save all argument
registers in this macro.)

float args are not saved: mcount does not clobber the
float regs and currently no asm function takes float
arguments anyway.

	[BZ #18707]
	* sysdeps/aarch64/Makefile (CFLAGS-mcount.c): Add -mgeneral-regs-only.
	* sysdeps/aarch64/sysdep.h (CALL_MCOUNT): Save argument registers.
