River Riddle b10c662514 [mlir][SideEffects] Replace the old SideEffects dialect interface with the newly added op interfaces/traits.
Summary:
The old interface was a temporary stopgap to allow for implementing simple LICM that took side effects of region operations into account. Now that MLIR has proper support for specifying memory effects, this interface can be deleted.

Alex Zinenko aff6bf4ff8 [mlir] support conversion of parallel reduction loops to std
Recently introduced support for converting sequential reduction loops to
CFG of basic blocks in the Standard dialect makes it possible to perform
a staged conversion of parallel reduction loops into a similar CFG by
using sequential loops as an intermediate step. This is already the case
for parallel loops without reduction, so extend the pattern to support
an additional use case.

Rob Suderman 69d757c0e8 Move StandardOps/Ops.h to StandardOps/IR/Ops.h
Summary:
NFC - Moved StandardOps/Ops.h to a StandardOps/IR dir to better match surrounding
directories. This is to match other dialects, and prepare for moving StandardOps
related transforms in out for Transforms and into StandardOps/Transforms.

Nagy Mostafa bc7b26c333 [MLIR] Allow Loop dialect IfOp and ForOp to define values
This patch implements the RFCs proposed here:
https://llvm.discourse.group/t/rfc-modify-ifop-in-loop-dialect-to-yield-values/463
https://llvm.discourse.group/t/rfc-adding-operands-and-results-to-loop-for/459/19.

It introduces the following changes:
- All Loop Ops region, except for ReduceOp, terminate with a YieldOp.
- YieldOp can have variadice operands that is used to return values out of IfOp and ForOp regions.
- Change IfOp and ForOp syntax and representation to define values.
- Add unit-tests and update .td documentation.
- YieldOp is a terminator to loop.for/if/parallel
- YieldOp custom parser and printer

Lowering is not supported at the moment, and will be in a follow-up PR.

Thanks.

Alex Zinenko 287d111023 Generalize implicit terminator into an OpTrait
Several groups of operations in different dialects (e.g. AffineForOp,
AffineIfOp; loop::ForOp, loop::IfOp) share the requirement for their regions to
contain 0 or 1 block, and for blocks to always have a specific terminator type.
Furthermore, this terminator may be omitted from the custom syntax.  Generalize
this behavior into OpTrait::SingleBlockImplicitTerminator, parameterized by the
terminator operation type.  This trait provides the verifier that checks the
presence of the terminator, and utility functions adding the terminator in case
of absence.
