  AMDGPU: Skip GetUnderlyingObject check in pointsToConstantMemory

Check the address space first before searching for the object
definition to save compile time. As an added bonus, this will now
treat casts to constant addrspace as constant.

We also seemed to be missing targeted tests for this, so add a few
missing other cases too.

  Log Message:
  -----------
  InstCombine: Broaden copy-constant-to-alloca optimization

Consider any constant memory type, not just global constants. AMDGPU
kernel parameters are effectively global constants, but appear as
either reads from an intrinsic derived pointer or function argument.
