True if the target uses physical regs (as nearly all targets do).
False for stack machines such as WebAssembly and other virtual-register machines. If true, all vregs must be allocated before PEI. If false, then callee-save register spilling and scavenging are not needed or used. If false, implicitly defined registers will still be assumed to be physical registers, except that variadic defs will be allocated vregs.
