[PATCH] Extra Command Line library functionality (option grouping and runtime inspection/modification)

[Daniel Liew]

Hi,

I've reworked my patches and redesigned a few bits. Now there is no
-help-cat. There is just the -help command line option. If two or more
option categories are declared then the behaviour of -help automatically
changes so it shows categorized output instead of uncategorized output.
When -help produces categorized output an option -help-list becomes
unhidden which will produce uncategorized output.

I have also documented my work in the Sphinx documentation in my patches.

The patches are attached. They were generated with git, they seem to
apply ok although git complains about trailing white space.

My git branch with these patches on can be found at
https://github.com/delcypher/llvm/tree/new-llvm-cmd

I also have a sample project that compiles against my API changes at
https://github.com/delcypher/sample-llvm-cmd

What do you suggest I do? I could e-mail the top 3 committers (by line)
who are...

Chris Latner
Andrew Trick
Jim Laskey

Thanks,
Dan Liew.
