a word.

David Given b3b7c684c6 Simplify MIPS relocations. Add RELS2 (for generic high-word relocations). Add
support for MIPS branch-and-jump relocations.

David Given 75308901bc Added hi[] and lo[] functions to the assembler; fix things enough that we now
get to the point of failing to link programs.

David Given 1d6ecddcf4 The MIPS backend is still full of holes, and cut-and-pasted PowerPC code, but
is beginning to look like an actual code generator.
