  AMDGPU: Use ConstantPool as source value for DAG lowered kernarg loads

This isn't quite a constant pool, but probably close enough for this
purpose. We just need some known invariant value address. The aliasing
queries against the real kernarg base pointer will falsely report
no aliasing, but for invariant memory it probably doesn't matter.

  -----------
  AMDGPU: Fix treating unknown mem operands as uniform (#168980)

The test changes are mostly GlobalISel specific regressions.
GlobalISel is still relying on isUniformMMO, but it doesn't really
have an excuse for doing so. These should be avoidable with new
regbankselect.

There is an additional regression for addrspacecast for cov4. We
probably ought to be using a separate PseudoSourceValue for the
access of the queue pointer.
