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.
Differential Revision: https://reviews.llvm.org/D74940
This patch implements the RFCs proposed here:
https://llvm.discourse.group/t/rfc-modify-ifop-in-loop-dialect-to-yield-values/463https://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.

Summary: This was a missed case when ValueRange was originally added, and allows for constructing a ValueRange from the arguments of a block.

This will enable future commits to reimplement the internal implementation of OpResult without needing to change all of the existing users. This is part of a chain of commits optimizing the size of operation results.

This is an initial step to refactoring the representation of OpResult as proposed in: https://groups.google.com/a/tensorflow.org/g/mlir/c/XXzzKhqqF_0/m/v6bKb08WCgAJ
This change will make it much simpler to incrementally transition all of the existing code to use value-typed semantics.

There are currently several different terms used to refer to a parent IR unit in 'get' methods: getParent/getEnclosing/getContaining. This cl standardizes all of these methods to use 'getParent*'.

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.

These ops should not belong to the std dialect.
This CL extracts them in their own dialect and updates the corresponding conversions and tests.
