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

4ad25e432d Entirely eliminate all patterns and expanders from this file. We shall go 
with an incremental approach rather than a revolutionary approach.

bbe664c8fb Move the 'Expander' node to later in the file, with the other experimental 
stuff.  The pattern becomes a list, add some stuff, add some comments.

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.
