Recently eXecute Only (XO) codegen was also allowed for armv6-M. Previously this was only implemented for ~armv7+, effectively if MOVW/MOVT is available. Regarding long calls, we remove the check for MOVW/MOVT when generating code for XO, which already was redundant as in the subtarget initialization we already check if XO is valid for the target. And targets that generate valid XO code should be able to handle the (wrapper globaladdress) node. Reviewed By: efriedma Differential Revision: https://reviews.llvm.org/D153782
