Also re-enable instr. scheduling pass.

Improve checking for constants in Multiply.
Simpler method to keep track of when a node is folded into its parent.
Several other bug fixes.

Also moved to the Scalar/ directory and renamed to "MultiDim".

first element of a structure type.  Before this would not be handled because
getStructOffset would either stop immediately (because StopEarly was true
and Offset = 0), or blast past the level we wanted.

Now ConvertableToGEP steps down through the type one level at a time, checking
the Offset and Scale conditions at each step

out that almost always the result of the add was the same as the GEP that
would be generated.  In this case, however, it wasn't, so bad things happened.

2. Allow negative scales in ConvertableToGEP, so that this loop from
   alloc_tree in the Olden health benchmark is correctly raised:

       for (i = 3; i >= 0; i--)
         fval[i] = alloc_tree(level - 1, label*4 + i + 1, new);

   Stepping through the array backwards caused a negative scale.

offset-from-FP will be before allocating space for a local variable.

Also use distinct names for the three types of SetMachineOperand
to avoid painful overloading problems and errors.

llvm-svn: 1904

instruction is actually generated for them.
Rename the different versions of SetMachineOperand.

llvm-svn: 1903

Fix constants in instructions generated for Phi elimination.

llvm-svn: 1902

but did not pass the arguments by reference!
Also added a function to get a register class by ID.

Also, use distinct names for the three types of SetMachineOperand to

Bug fix in converting-int-to-float.  Other minor stuff.

wrong register class for saving CC registers.
Also, use distinct names for the three types of SetMachineOperand.

Different labels were generated for the same name in different passes.
