* Switch FoldingSet::AddString to StringRef based API.Daniel Dunbar2009-09-221-11/+3

* Several changes together in a murky mess:Chris Lattner2009-09-201-84/+102
| | | | | | | | | | | | 1. Change some "\n" -> '\n'. 2. eliminte some std::string's by using raw_ostream::indent. 3. move a bunch of code out of the main arg parser routine into a new static HandlePrefixedOrGroupedOption function. 4. Greatly simplify the implementation of getOptionPred, and make it avoid splitting prefix options at = when that doesn't match a non-prefix option. llvm-svn: 82362
