Converting floats and doubles to integers now works, as much as these ever do
on MIPS; turns out that it can't (or at least can't in qemu) reliably turn
INT_MIN from a double to an int.

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

Add the bitset helpers. We now have enough helpers for the tests to run (and
massively fail).

Add the .dataf4 and .dataf8 directives to the assembler --- manually converting
floats and doubles to bytes is not fun. It might even work!

Yikes! Turns out that FPU registers are only 32 bits wide, and doubles are
stored in pairs, just like on the PowerPC!

a word.

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.

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