This is the regression test for the change to InstructionCombining.cpp
that I made today.  It illustrates that the old version of the code
would crash if the RHS of a multiplication were a ConstantExpr that
could not be resolved into a ConstantInt or ConstantFP.

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.

old global functions.  As it happens, none of them really have anything
to do with TargetInstrInfo.

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.)
