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.

a376ee2d13 Convert many of the virtual TargetInstrInfo methods used as helper

1b4aeb5cec As it happens, none of these TargetInstrInfo methods which are only 
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)
