Dirty, dirty patch that makes SFX work on x86 Linux

The attached patch gets things working on Linux.  It's really dirty, and does
the bare minimum to get it working without doing so in a nice manner.  It
passes all of the JSCore tests with both WREC and CTI enabled.  On SunSpider,
it gives a 1.29x speedup.

Things that need fixed:
1) The inline assembly mess that I mentioned in a previous comment.
2) I'm not sure why Linux needs the same emitRestoreArgumentReference madness
that Windows needs.  Perhaps Gavin can shed some light on this?
3) We have no PLATFORM macro for Linux, only the generic UNIX macro.  Do all
x86 Unix platforms use the same ABI?  Do we need to introduce a LINUX define
and target some of these changes specifically at Linux?
