346c1f60db the switch from std::map -> StringMap caused --help output to be in 
non-sorted order, restore the sort.

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.

This requires StringRef'izing ProvideOption which I also did.

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.

b8b2ef98f4 Try to speed up the slowest parts of the CommandLine library 
- Replace std::map<std::string with StringMap
- Eliminate unnecessary std::string copies
- ~10% speed-up for clang's testsuite on my machine (debug build)

149ac38d37 Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't 
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.

7b789f8cba Added an abstract superclass, MCDisassembler, for 
all disassemblers.

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.

53f0d68f87 Make LLVM command-line tools overwrite their output files without -f. 
This is conventional command-line tool behavior. -f now just means
"enable binary output on terminals".

Add a -f option to llvm-extract and llvm-link, for consistency.

Remove F_Force from raw_fd_ostream and enable overwriting and
truncating by default. Introduce an F_Excl flag to permit users to
enable a failure when the file already exists. This flag is
currently unused.

Update Makefiles and documentation accordingly.
