[AArch64] Mark function calls as possibly changing FPCR

This patch does the same changes as D111433 for PowerPC and D139549 for
X86, - in the strictfp function all calls are marked as implicit defs of
FPCR. It prevents from moving FP operations across function calls, which
may change rounding mode, as fesetround does.
