[frontend] Fix the handling of -debug-constraints-attempt.

Browse Source 
StringRef::getAsInteger returns true, not false, when an error occurs.
Explicitly set the radix to 10, instead of inferring the radix.
For the invalid argument value diagnostic, switch the order of the argument string and the value.
