[PATCH] D149211: [GlobalISel][InlineAsm][X86]Fallback on DAG ISel when lowering inline assembly

[Mingming Liu via Phabricator via llvm-commits]

https://gcc.godbolt.org/z/vq4nGG793 shows setting `global-isel-abort` to `DisableWithDiag` indeed works.

Thinking back what I have in mind when writing this patch, I misunderstood how I shall use `fallBackToDAGISel` (thought the fallback path would also call this method )-> in fact, when IRTranslator handles translation error <https://github.com/llvm/llvm-project/blob/7f96ce5e133be54891af177adbf8952d413e0f85/llvm/lib/CodeGen/GlobalISel/IRTranslator.cpp#L238>, it sets properties on machine-function; and let codegen pass builder to decide whether to restore machine function and falls back to selection-dag-based ISel (decided by `-global-isel-abort` mode)
