River Riddle ed5fe2098b Remove PassResult and have the runOnFunction/runOnModule functions return void instead. To signal a pass failure, passes should now invoke the 'signalPassFailure' method. This provides the equivalent functionality when needed, but isn't an intrusive part of the API like PassResult.

River Riddle c6c534493d Port all of the existing passes over to the new pass manager infrastructure. This is largely NFC.

River Riddle 3e656599f1 Define a PassID class to use when defining a pass. This allows for the type used for the ID field to be self documenting. It also allows for the compiler to know the set alignment of the ID object, which is useful for storing pointer identifiers within llvm data structures.

River Riddle 48ccae2476 NFC: Refactor the files related to passes. 
* PassRegistry is split into its own source file.
* Pass related files are moved to a new library 'Pass'.

River Riddle bf9c381d1d Remove InstWalker and move all instruction walking to the api facilities on Function/Block/Instruction.

River Riddle 870d778350 Begin the process of fully removing OperationInst. This patch cleans up references to OperationInst in the /include, /AffineOps, and lib/Analysis.

River Riddle de2d0dfbca Fold the functionality of OperationInst into Instruction. OperationInst still exists as a forward declaration and will be removed incrementally in a set of followup cleanup patches.

Feng Liu dfee0a6e9b Make PrintOpStatsPass a module pass 
PrintOpStatsPass is maintaining state (op stats ) across functions and doing
per-module work - it should be a module pass.

Chris Lattner dffc589ad2 Extend InstVisitor and Walker to handle arbitrary CFG functions, expand the 
Function::walk functionality into f->walkInsts/Ops which allows visiting all
instructions, not just ops.  Eliminate Function::getBody() and
Function::getReturn() helpers which crash in CFG functions, and were only kept
around as a bridge.

This is step 25/n towards merging instructions and statements.

Chris Lattner 456ad6a8e0 Standardize naming of statements -> instructions, revisting the code base to be 
consistent and moving the using declarations over.  Hopefully this is the last
truly massive patch in this refactoring.

This is step 21/n towards merging instructions and statements, NFC.

Chris Lattner 69d9e990fa Eliminate the using decls for MLFunction and CFGFunction standardizing on 
Function.

This is step 18/n towards merging instructions and statements, NFC.

Chris Lattner 5187cfcf03 Merge Operation into OperationInst and standardize nomenclature around 
OperationInst.  This is a big mechanical patch.

This is step 16/n towards merging instructions and statements, NFC.

Chris Lattner 776b035646 Eliminate the Instruction, BasicBlock, CFGFunction, MLFunction, and ExtFunction classes, using the Statement/StmtBlock hierarchy and Function instead. 
This *only* changes the internal data structures, it does not affect the user visible syntax or structure of MLIR code.  Function gets new "isCFG()" sorts of predicates as a transitional measure.

This patch is gross in a number of ways, largely in an effort to reduce the amount of mechanical churn in one go.  It introduces a bunch of using decls to keep the old names alive for now, and a bunch of stuff needs to be renamed.

This is step 10/n towards merging instructions and statements, NFC.

Jacques Pienaar 057984d05d Move print op stats pass to analysis. 
Move PrintOpStatsPass out of tools and to other passes (moved to Analysis as it
doesn't modify the program but it is different than the other analysis passes
as it is only consumer at present is the user).
