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 ensures that we're building and testing the CompileOnDemand layer, at least
in a basic way.
Currently x86-64 only, and with limited to no library calls enabled (depending
on host platform). Patches welcome. ;)
To enable access to the lazy JIT, this patch replaces the '-use-orcmcjit' lli
option with a new option:
'-jit-kind={ mcjit | orc-mcjit | orc-lazy }'.
All regression tests are updated to use the new option, and one trivial test of
the new lazy JIT is added.
