[CompilerRT] use .p2align, .balign instead of .align
The .align statements in ARM assembly routines is actually meant to be a power
of 2 alignment (e.g. .align 2 == 4 byte alignment, not 2). Switch to using
.p2align. .p2align is guaranteed to be a power-of-two alignment always and much
more explicit.
The .align in the case of x86_64 is byte alignment, use .balign instead of
.align.
