Prevents the post-RA scheduler from modifying the prologue sequences emitting by frame lowering. This is roughly similar to what we do for other targets: TargetInstrInfo::isSchedulingBoundary checks isPosition(), which checks for CFI_INSTRUCTION. isSEHInstruction is taken from D50288; it'll land with whatever patch lands first. Differential Revision: https://reviews.llvm.org/D53851 llvm-svn: 345634
