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.
