[GIT PULL] jump label: add jump label code

[Steven Rostedt]

Ingo,

I finally got around to doing some basic tests. The thing that
took the longest, was setting up all my distcc computers with gcc 2.5.1.
I also hit a little glitch in one of my tests that would trigger
RCU stalls, but that's another story.

Anyway, I took Jason's patches and applied them, with a few
formatting clean ups (basically, shortened function prototypes).

I added two patches at the end of the series to remove the duplicate
structure and also to remove the dependency on !CC_OPTIMIZE_FOR_SIZE.

Andi,

I saw your patches but have not had time to take a deeper look at
them. If you want, you can rebase them against this tree.

Thanks,
