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

[PowerPC] Don't return unsupported register classes for asm constraints As a follow-up to r251566, do the same for the other optionally-supported register classes (mostly for vector registers). Don't return an unavailable register class (which would cause an assert later), but fail cleanly when provided an unsupported inline asm constraint. llvm-svn: 251575
