In cases where the to-be-allocated node size with padding exceeds BLOCK_SIZE
but without padding doesn't, a new block is not created and no padding is done
to the previous instruction, causing a misaligned pointer to be returned.
v2: Per Ilia Mirkin's suggestion, remove the extra condition in the first
if statement, let it unconditionally pad the last instruction if needed.
The updated currentPos will then be taken into account in the
block size checking.
This fixes crash seen with lightsmark and Optuma apitraces
