This commit aligns trampolines for THUMB and ARM instructions
(CALL/JUMP24 and THM_JUMP24/THM_PC22).
According to the ARM technical reference in section "Register-relative
and PC-relative expressions":
In Thumb code:
- For B, BL, CBNZ, and CBZ instructions, the value of the PC is the
address of the current instruction plus 4 bytes.
- For all other instructions that use labels, the value of the PC is
the address of the current instruction plus 4 bytes, with bit[1]
of the result cleared to 0 to make it word-aligned.
