This patch adds a new class, OrcI386, which contains the hooks needed to
support lazy-JITing on i386 (currently only for Pentium 2 or above, as the JIT
re-entry code uses the FXSAVE/FXRSTOR instructions).
Support for i386 is enabled in the LLI lazy JIT and the Orc C API, and
regression and unit tests are enabled for this architecture.

This class is turning into a useful interface, rather than an implementation
detail, so I'm dropping the 'Base' suffix.
No functional change.

Bypassing LLVM for this has a number of benefits:
1) Laziness support becomes asm-syntax agnostic (previously lazy jitting didn't
work on Windows as the resolver block was in Darwin asm).
2) For cross-process JITs, it allows resolver blocks and trampolines to be
emitted directly in the target process, reducing cross process traffic.
3) It should be marginally faster.
