Merge MRI::isPhysRegOrOverlapUsed() into isPhysRegUsed().
All callers of these functions really want the isPhysRegOrOverlapUsed() functionality which also checks aliases. For historical reasons, targets without register aliases were calling isPhysRegUsed() instead. Change isPhysRegUsed() to also check aliases, and switch all isPhysRegOrOverlapUsed() callers to isPhysRegUsed(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166117 91177308-0d34-0410-b5e6-96231b3b80d8
