96563df090 Specify an asm string and operands lists for a bunch of instructions. 
This only really covers no-operand instructions so far.

2e1f51b8a5 Initial cut at an asm writer emitter. So far, this only handles emission of 
instructions, and only instructions that take no operands at that!

365f54c7bc Convert a few assertions with side-effects into regular old runtime checks. 
These side-effects seem to make a difference when using llc -march=sparcv9
in Release mode (i.e., with -DNDEBUG); when they are left out, lots of
instructions just get dropped on the floor, because they never end up
in the schedule.
