Akira Hatanaka 489decec67 [inline asm] Add a check in InlineAsm::ConstraintInfo::Parse to make sure '{' ...

follows '~' in a clobber constraint string.

Previously llc would hit an llvm_unreachable when compiling an inline-asm
instruction with malformed constraint string "~x{21}". This commit enables
LLParser to catch the error earlier and print a more helpful diagnostic.
