3a20fca97c don't use count + insert, just do insert + failure. Also, instead of deleting from 
the middle of a vector, swap the last element in and pop_back.  Also saves 330 bytes :)

6a6a75896d Several changes together in a murky mess: 
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.

Add another line to the ConstantExprFold test to demonstrate the GEPs may not
wrap around in either the signed or unsigned senses.

d402d7374a Here's fun! It turns out that these filter functions can be internal. If they're 
internal, they shouldn't use the indirect pointer stuff. In the case of
throw_rethrow_test, it was marked as 'internal' and calculated its own offset to
its contents.

This requires StringRef'izing ProvideOption which I also did.

ca1f29ee1b Value* were never meant to be const. Removing constness from the constant 
folder removes a lot of const_casting and requires no changes to clang or
llvm-gcc.

85478e8cd1 convert a bunch more stuff to use StringRef. The ArgName arguments are now 
stringref because they may not be nul terminated.  For options like -Lfoo
this now avoids a O(n)  temporary std::strings where N is the length of 
the string after -L.

f8d05d7ce6 When computing live intervals for earlyclobber operands, 
we pushed the beginning of the interval back 1, so the
interval would overlap with inputs that die.  We were
also pushing the end of the interval back 1, though,
which means the earlyclobber didn't overlap with other
output operands.  Don't do this.  PR 4964.
