  -----------
  AMDGPU/GlobalISel: Partially move constant selection to patterns (#100786)

This is still relying on the manual code for splitting 64-bit
constants, and handling pointers.

We were missing some of the tablegen patterns for all immediate types,
so this has some side effect DAG path improvements. This also reduces
the diff in the 2 selector outputs.
