MCParser: Reject .balign with non-pow2 alignments. GNU as rejects them and there are configure scripts in the wild that check if the assembler rejects ".align 3" to determine whether the alignment is in bytes or powers of two. llvm-svn: 175360

[MC] Reject byte alignment if larger than or equal to 2**32 This is consistent with the resolution to power-of-2 alignments. Otherwise, emitCodeAlignment and emitValueToAlignment cannot handle alignments larger than 2**32 and will trigger assertion failure (PR35218). Note: GNU as as of 2.35 will use 1 for such a large byte `.align`
