Add patches to let mozilla-firefox 4.0 at least build on sparc64.

- disable tracejit/methodjit
- add fix for https://bugzilla.mozilla.org/show_bug.cgi?id=618485
- add fix for https://bugzilla.mozilla.org/show_bug.cgi?id=589754
- don't force-enable assembler/jit on sparc64

It still doesn't run (endless loop at startup) due to 64-bits
jsval_layout (see https://bugzilla.mozilla.org/show_bug.cgi?id=577056)
but at least patches are in cvs, and the js shell can run simple things.
No change for other archs.
