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

Added some very untested csa and csb implementations, based on the PowerPC
ones.

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

Rework floating point conversion. Bash enough of the table into workingness
that the libraries build now.

Precisely one stack hreg gets allocated for each vreg/congruence group for
eviction; this prevents us from having to worry about moving values from stack
slot to stack slot, which is hard.

MIPS appears to hate converting unsigneds to floats and vice versa.

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.
