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.

Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg of
...
physical registers. This is especially critical for the later two since they
start the live interval of a super-register. e.g.
%DO<def> = INSERT_SUBREG %D0<undef>, %S0<kill>, 1
If this instruction is eliminated, the register scavenger will not be happy as
D0 is not defined previously.
This fixes PR5055.

Also, reorganize loop verification. Make the LoopPass infrastructure
