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, add a flag to marked nodes that do not need code because they
have been folded into the user (parent in the BURG tree).

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

* AllocationInst now always has an array size operand

* Move AllocationInst ctor to iMemory.cpp
* AllocationInst's always have one operand, even if it is a uint 1

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.
