35b305863a Bugfix for the CommaSeparated option. The original code was adding the whole 
string at the end of the list, instead of the last comma-separated string.

1d75d3a8ae Roll back r82348, which introduced an infinite loop in ParseCStringVector() that 
a trivial unittest would have caught.  This revision also adds the trivial
unittest.

b40b7e3faf 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 :)

b168737a74 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.

99c5c7b7df 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.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

c25e7581b9 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.
