Andy Davis a560f2c646 Affine Loop Fusion Utility Module (1/n). ...

*) Adds LoopFusionUtils which will expose a set of loop fusion utilities (e.g. dependence checks, fusion cost/storage reduction, loop fusion transformation) for use by loop fusion algorithms. Support for checking block-level fusion-preventing dependences is added in this CL (additional loop fusion utilities will be added in subsequent CLs).
    *) Adds TestLoopFusion test pass for testing LoopFusionUtils at a fine granularity.
    *) Adds unit test for testing dependence check for block-level fusion-preventing dependences.

FoldUtils.cpp

Unify the 'constantFold' and 'fold' hooks on an operation into just 'fold'. This new unified fold hook will take constant attributes as operands, and may return an existing 'Value *' or a constant 'Attribute' when folding. This removes the awkward situation where a simple canonicalization like "sub(x,x)->0" had to be written as a canonicalization pattern as opposed to a fold.

Utils.cpp

Refactor FunctionAttr to hold the internal function reference by name instead of pointer. The one downside to this is that the function reference held by a FunctionAttr needs to be explicitly looked up from the parent module. This provides several benefits though:
