x86 asm: Replace .align with .balign

Browse Source 
The .align directive used to align storage locations is
ambiguous. On some platforms and assemblers it takes a byte count,
on others the argument is interpreted as a shift value. The current
usage expects the first interpretation.

Replace it with the unambiguous .balign directive which always
expects a byte count, regardless of platform and assembler.
