[PATCH] [compiler-rt] use .p2align instead of .align

[Saleem Abdulrasool]

  I had a look at the output, you are right, the i386 version is supposed to be aligned to 4.  I would like to make the change to the ARM version.  I realise that this would have no functional difference, but makes it more clear that the alignment is meant to be a power of two and not the raw value (like the case is for i386).  Would you be against that?
