9dbef0bf96 Rename FunctionAttr to SymbolRefAttr.
This allows for the attribute to hold symbolic references to other operations than FuncOp. This also allows for removing the dependence on FuncOp from the base Builder.

2e1187dd25 Globally change load/store/dma_start/dma_wait operations over to affine.load/store/dma_start/dma_wait.
In most places, this is just a name change (with the exception of affine.dma_start swapping the operand positions of its tag memref and num_elements operands).
Significant code changes occur here:
*) Vectorization: LoopAnalysis.cpp, Vectorize.cpp
*) Affine Transforms: Transforms/Utils/Utils.cpp

898cf0e968 LoopFusion: adds support for computing forward computation slices, which will enable fusion of consumer loop nests into their producers in subsequent CLs.

1de0f97fff LoopFusionUtils CL 2/n: Factor out and generalize slice union computation.
*) Factors slice union computation out of LoopFusion into Analysis/Utils (where other iteration slice utilities exist).
    *) Generalizes slice union computation to take the union of slices computed on all loads/stores pairs between source and destination loop nests.
    *) Fixes a bug in FlatAffineConstraints::addSliceBounds where redundant constraints were added.
    *) Takes care of a TODO to expose FlatAffineConstraints::mergeAndAlignIds as a public method.

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.
