eliminate the duplicate detection loop, moving it into the loop that populates the Opts vector in the first place.

the middle of a vector, swap the last element in and pop_back.  Also saves 330 bytes :)

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.

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.

More still left to eliminate.

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

 - As best I can tell, we have eliminated all the code which used to require a
   larger buffer size.

working. To support this, add an is_displayed() function to raw_ostream,
and generalize Process::StandardOutIsDisplayed and friends in order to
support it.

Also, call RemoveFileOnSignal before creating a file instead of after, so
that the file isn't left behind if the program is interrupted between when
the file is created and RemoveFileOnSignal is called.

While here, add a -S to llvm-extract and port it to IRReader so that it
supports assembly input.

Modified the MemoryObject to support 64-bit address
spaces, regardless of the LLVM process's address
width.

Modified the Target class to allow extraction of a
MCDisassembler.

Also, StringRefize additional Triple constructor.

1. DUPMAX is defined in regcomp.c, no need to redefine it in regutils.
2. MSVC doesn't like snprintf, use _snprintf instead.
