  GlobalISel: Fix maxScalarIf predicate check

The std::function itself was tested, not the result of the actual
query. It seems like there should be a warning for this. Inline the
check to avoid this.

  GlobalISel: Drop original type pointeriness in minScalarSameAs

It is not useful to report WidenScalar for a pointer value, so always
report a scalar value with the target size. This allows using this to
clamp the scalar operand to the pointer size in operations like
G_PTR_ADD or G_PTRMASK.

  -----------
  GlobalISel: Add scalarSameSizeAs LegalizeRule

Widen or narrow a type to a type with the same scalar size as
another. This can be used to force G_PTR_ADD/G_PTRMASK's scalar
operand to match the bitwidth of the pointer type. Use this to
disallow narrower types for G_PTRMASK.
