Fix __attribute__((force_align_arg_pointer)) misalignment bug
The force_align_arg_pointer attribute was using a hardcoded 16-byte
alignment value which in combination with -mstack-alignment=32 (or
larger) would produce a misaligned stack which could result in crashes
when accessing stack buffers using aligned AVX load/store instructions.
Fix the issue by using the "stackrealign" function attribute instead
of using a hardcoded 16-byte alignment.
