  Log Message:
  -----------
  [AArch64][GlobalISel] Fix incorrect selection of monotonic s32->s64 anyext load.

This load isn't selected by tablegen due to the anyext, but wasn't generating
a subreg_to_reg. Maybe it shouldn't be formed at all during the combiner but to stop
crashes later in codegen select it manually for now.
