Looking at it in the debugger, validateOutputConstraint and
validateInputConstraint are also called earlier from Sema::ActOnAsmStmt
after parsing.  It seems you are implying that the string literals should be
modified at some point before the validate and other functions are called
that use the strings.

If so, can you tell me how to do it?  It seems that the expressions and so
forth are meant to be immutable after being created.

Otherwise, can you hold my hand a bit?  As I'm not sure what to do.
