Summary: The current implementation of isConstantPhysReg() checks for defs of physical registers to determine if they are constant. Some architectures (e.g. AArch64 XZR/WZR) have registers that are constant and may be used as destinations to indicate the generated value is discarded, preventing isConstantPhysReg() from returning true. This change adds a TargetRegisterInfo hook that overrides the no defs check for cases such as this.
