b2cf39d1a4 Fix test/Regression/Analysis/BasicAA/2004-07-28-MustAliasbug.llx
This also fixes the miscompilation of MallocBench/gs with dead store
elimination enabled.

7de9b55c7e Don't derive from ValueSet to implement class LiveRange; instead, use a
SetVector<Value *> data member.
Add << operator for LiveRanges (a dumb one, for now.)

4325ca6606 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.

c9b9016d72 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.

a71776e676 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.)
