  GlobalISel: Add computeKnownBitsForTargetInstr

I think we can save the MRI argument from these since it's in
GISelKnownBits already, but currently not accessible.

Implementation deferred to avoid dependency on other patches.

  Log Message:
  -----------
  GlobalISel: Prepare to allow other target unit tests

Currently all GlobalISel unittests use a hardcoded AArch64 target
machine. Factor this so I can write some for AMDGPU specific known
bits unittests.
