[PATCH] D45376: Fix PR34170: Crash on inline asm with 64bit output in 32bit GPR

[Thomas Preud'homme via Phabricator via llvm-commits]

Add support for inline assembly with output operand that do not naturally go in the register class it is constrained to (eg. double in a 32-bit GPR as in the PR). Also add support for matching input in similar situation. Note that regular input is already handled by existing code.
