  -----------
  AMDGPU/GlobalISel: Widen 16-bit shift amount sources

This should be legal, but will require future selection work. 16-bit
shift amounts were already removed from being legal, but this didn't
adjust the transformation rules.

  -----------
  AMDGPU/GlobalISel: Fix argument lowering for vectors of pointers

When these arguments are broken down by the EVT based callbacks, the
pointer information is lost. Hack around this by coercing the register
types to be the expected pointer element type when building the
remerge operations.

  Log Message:
  -----------
  GlobalISel: Don't assert on MoreElements creating vectors

If the original type was a scalar, it should be valid to add elements
to turn it into a vector.

Tests included with following legalization change.
