e302a7eb43 Add support for copying bool constants to registers.
Disable the code that copies long constants to registers - it looks fishy.
Implement some simple casts: integral, smaller than longs, and equal-width
 or narrowing only.

d54c38b2f4 It's setting up the call args right now, but on the callee side, it's
trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

4d0cda4d5c This is a start on handling setcc instructions. As the comment notes, we
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.

2d4fa8faac Preliminary support for getting 64-bit integer constants into registers.
Preliminary support for division. It's gross because you have to initialize
the "Y" register, which is the top 32 bits of the thing you're dividing.
