[PATCH] D53765: [RFC prototype] Implementation of asm-goto support in LLVM

[Craig Topper via Phabricator via llvm-commits]

-Add a new isAsmGotoTarget flag to MachineBasicBlock. Use it to preserve predecessors/successors in a few places similar to isEHPad. Probably more work to do here, but I think it at least fixes  https://github.com/ClangBuiltLinux/linux/issues/319
-Remove SelectionDAGBuilder support for doing anything with CallBr other than inline assembly. The code can't be tested today so there's really no point in having it. Assuming inline assembly only made setting the flag above a little simpler.
