Remove la; turns out that the assembler gets upset if you ask it to
generate more than one fixup per instruction (I think).

Make sure li works properly when loading fixed up values which end up as 0. Use
lui rather than li to load high values.

a word.

support for MIPS branch-and-jump relocations.

Added hi[] and lo[] functions to the assembler; fix things enough that we now
get to the point of failing to link programs.

The examples all compile now (probably incorrectly, and the libc doesn't
compile yet).

The MIPS backend is still full of holes, and cut-and-pasted PowerPC code, but
is beginning to look like an actual code generator.
