Generate PLT thumb stub for an ARM PLT entry only when at least one Thumb instruction branches to that entry. Warning: To save space, this commit reuses the bit 0 of entries of got_offsets array. The GOT offset is thus saved in a 31 bit value. Make sure to divide by 2 (right shift by 1) an offset before storing it there and conversely to multiply the value by 2 (left shift by 1) before using it.
