Subject: Multi-target support

This CL represents a step towards splitting out the target dependent
and target independent portions of the compiler, and also adds in the
beginning of a MIPS compiler based on the MIPS AOSP Jit submission.

More polish is clearly needed, but the split is here probably pretty
close.  The MIPS code will not compile at this point (and there is no
makefile target at present), but it's pretty close.

There should be no changes in functionality of the Arm compiler in this
CL - just moved stuff around.
