PCALIGN also changes the function alignment. If a function has one or more PCALIGN directives,
its address will be aligned to the same or coarser boundary, which is the maximum of all the
alignment values.

In the following example, the function Add is aligned with 128 bytes.

Examples:

	TEXT ·Add(SB),$40-16
	MOVD $2, R0
	PCALIGN $32
	MOVD $4, R1
	PCALIGN $128
	MOVD $8, R2
