Evan Cheng 83e0d481ae Make ARM and Thumb2 32-bit immediate materialization into a single 32-bit pseudo 
instruction. This makes it re-materializable.

Thumb2 will split it back out into two instructions so IT pass will generate the
right mask. Also, this expose opportunies to optimize the movw to a 16-bit move.
