Fix an assert in SelectionDAGBuilder when processing inline asm When processing inline asm that contains errors, make sure we can recover gracefully by creating an UNDEF SDValue for the inline asm statement before returning from SelectionDAGBuilder::visitInlineAsm. This is necessary for consumers that don't exit on the first error that is emitted (e.g. clang) and that would assert later on. Fixes PR24071. Patch by Diana Picus. llvm-svn: 269811

ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. llvm-svn: 205090
