The BLX instruction is encoded differently than the BL, because why not? In
particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0'
always. Going through the BL fixup encoding was trashing the "bit 0 is '0'"
invariant.
Attempt to get the encoding at slightly more correct with this.
