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.

VLDR fixups need special handling under Thumb. While the encoding is the same,

the order of the bytes in the data stream is flipped around.

Fix .o emission of ARM movt/movw. MCSymbolRefExpr::VK_ARM_(HI||LO)16 for the .o path now works for ARM.

Note: lo16AllZero remains in ARMInstrInfo.td - It can be factored out when Thumb movt is repaired.
Existing tests cover this update.
