fetch width when aligning @code{LOOP} instructions (except if the first
instruction in the loop is a 64-bit instruction).
Similarly, the @code{ENTRY} instruction must be aligned on a 0 mod 4
byte boundary. The assembler satisfies this requirement by inserting
zero bytes when required. In addition, labels immediately preceding the
@code{ENTRY} instruction will be moved to the newly aligned instruction
location.
Previous versions of the assembler automatically aligned @code{ENTRY}
instructions to 4-byte boundaries, but that alignment is now the
programmer's responsibility.
