Complete MIPS code generation support
With this CL code generation for MIPS is complete (though untested on
actual hardware). Core and the boot classpath compile without issue.
The primary thrust here was to support expanding of short branch
sequences to long form during assembly if the displacement field overflowed.
That led to a general cleanup of creation on LIR nodes outside of the
Also introduced is a README to describe the state of MIPS support, as well
as memory barrier handling.
