  Log Message:
  -----------
  [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`
