If an inline assembly operand has multiple constraints (e.g. "Ir" for immediate or register) and an operand modifier (E.g. "w" for "print register as wN") then we need to decide behaviour when the modifier doesn't apply to the constraint. Previousely produced some combination of an assertion failure and a fatal error. GCC's behaviour appears to be to ignore the modifier and print the operand in the default way. This patch should implement that. llvm-svn: 194024
