https://reviews.llvm.org/D54980 This provides a standard API across GISel passes to observe and notify passes about changes (insertions/deletions/mutations) to MachineInstrs. This patch also removes the recordInsertion method in MachineIRBuilder and instead provides method to setObserver. Reviewed by: vkeles. llvm-svn: 348406
