[X86] Fix assertion in subreg extraction This assert fires when attempting to extract a subregister from the global PIC base register. This virtual register SD node is not in the VRBaseMap, so we shouldn't call getVR to look it up there. If this is a RegisterSDNode, we should be able to use the virtual register directly. Fixes PR38385 llvm-svn: 339056

[ELF] Fix large code model MIR verifier errors Instead of using the MOVGOT64r pseudo, use the existing MO_PIC_BASE_OFFSET support on symbol operands. Now I don't have to create a "scratch register operand" for the pseudo to use, and the register allocator can make better decisions. Fixes some X86 verifier errors tracked in PR27481. llvm-svn: 345219
