7baad7365a Perform explicit instantiations in the proper namespace, since Clang diagnoses this ill-formity.

5551c207cd Move the handling of CommaSeparated options into ProvideOption. 
Makes '--comma-separated val1,val2' mean the same thing as
'--comma-separated=val1,val2' (that is, 'val1' and 'val2' are not lumped
together as 'val1,val2'). Also declutters the main loop a bit.

713fd3564a Revert CPU detection code to return "generic" instead of an empty string in case 
of failure. The x86 target didn't like empty cpu names and broke x86 tests on
non-x86 buildbots.

08506ee6b0 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.

a75d6bf3a8 Roll back r82348, which introduced an infinite loop in ParseCStringVector() that 
a trivial unittest would have caught.  This revision also adds the trivial
unittest.

28610b9878 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 :)

e7c1e210c7 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.

This requires StringRef'izing ProvideOption which I also did.

3b8adaf488 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.

aecd74d895 convert a bunch of std::strings to use StringRef. This should eliminate 
a massive number of temporary strings created when parsing a command line.
More still left to eliminate.

- Eliminate unnecessary std::string copies
- ~10% speed-up for clang's testsuite on my machine (debug build)

fbcc663cbf 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").

56d0659726 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.
