56d38c6ca1 UnitTests 2003-05-26-Shorts and 2003-07-09-LoadShorts have been fixed; 
2003-05-22-VarSizeArray is broken.

2003-07-09-LoadShorts.

71698285e8 This change fixed a bug in the function visitMul. The prior version 
assumed that a constant on the RHS of a multiplication was either an
IntConstant or an FPConstant.  It checked for an IntConstant and then,
if it did not find one, did a hard cast to an FPConstant.  That code
would crash if the RHS were a ConstantExpr that was neither an
IntConstant nor an FPConstant.  This version replaces the hard cast
with a dyn_cast.  It performs the same way for IntConstants and
FPConstants but does nothing, instead of crashing, for constant
expressions.

The regression test for this change is 2004-07-27-ConstantExprMul.ll.

a376ee2d13 Convert many of the virtual TargetInstrInfo methods used as helper 
functions in SparcV9InstrSelection and SparcV9PreSelection into regular
old global functions.  As it happens, none of them really have anything
to do with TargetInstrInfo.

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.)

3ada3e3f82 ADDI can take several forms, including: 
addi r1, r2, 0
  addi r1, <frame index #n>, 0

to be considered a reg-to-reg copy.
