  Log Message:
  -----------
  [TargetLowering] move "o" and "X" constraint handling to base class

These constraints are machine agnostic; there's no reason to handle
these per-arch. If arches don't support these constraints, then they
will fail elsewhere during instruction selection. We don't need virtual
calls to look these up; TargetLowering::getInlineAsmMemConstraint should
only be overridden by architectures with additional unique memory
constraints.
