- NFC - on any pass/utility logic/output.
- Resolve TODO; the method building loop trip count maps was
creating and deleting affine.apply ops (transforming IR from under
analysis!, strictly speaking). Introduce AffineValueMap::difference to
do this correctly (without the need to create any IR).
- Move AffineApplyNormalizer out so that its methods are reusable from
AffineStructures.cpp; add a helper method 'normalize' to it. Fix
AffineApplyNormalize::renumberOneDim (Issue tensorflow/mlir#89).
- Trim includes on files touched.
- add test case on a scenario previously not covered

- add missing canonicalization pattern to fold memref_cast + dim to
dim (needed to propagate constant when folding a dynamic shape to
a static one)
- also fix an outdated/inconsistent comment in StandardOps/Ops.td

This allows for users other than those on the command line to apply a textual description of a pipeline to a given pass manager.

SPIR-V recently publishes v1.5, which brings a bunch of symbols
into core. So the suffix "KHR"/"EXT"/etc. is removed from the
symbols. We use a script to pull information from the spec
directly.
Also changed conversion and tests to use GLSL450 instead of
VulkanKHR memory model. GLSL450 is still the main memory model
supported by Vulkan shaders and it does not require extra
capability to enable.

This allows for explicitly specifying the pipeline to add to the pass manager. This includes the nesting structure, as well as the passes/pipelines to run. A textual pipeline string is defined as a series of names, each of which may in itself recursively contain a nested pipeline description. A name is either the name of a registered pass, or pass pipeline, (e.g. "cse") or the name of an operation type (e.g. "func").
For example, the following pipeline:
$ mlir-opt foo.mlir -cse -canonicalize -lower-to-llvm
Could now be specified as:
$ mlir-opt foo.mlir -pass-pipeline='func(cse, canonicalize), lower-to-llvm'
This will allow for running pipelines on nested operations, like say spirv modules. This does not remove any of the current functionality, and in fact can be used in unison. The new option is available via 'pass-pipeline'.

This CL adds support for serializing and deserializing spv.loop ops.
This adds support for spv.Branch and spv.BranchConditional op
(de)serialization, too, because they are needed for spv.loop.

This better reflects how this kind of expressions is used and avoids the
potential confusion since the expression can take negative values. Term
expressions comprise dimensions, symbols and stripe expressions. In an SDBM
domain, a stripe expression always corresponds to a variable, input or
temporary. This expression can appear anywhere an input variable can,
including on the LHS of other stripe expressions.

If the composite is a constant, we can fold it away. This only
supports vector and array constants for now, given that struct
constant is not supported in spv.constant yet.

Since we apply nudging for the zero point to make sure the nudged zerop points
can be in the range of [qmin, qmax], the constraint that rmin / rmax should
stride zero isn't necessary.
This also matches the documentation of tensorflow's FakeQuantWithMinMaxArgs op,
where min and max don't need to stride zero:

* Add GraphTraits that treat a block as a graph, Operation* as node and use-relationship for edges;
- Just basic graph output;
* Add use iterator to iterate over all uses of an Operation;
* Add testing pass to generate op graph;
This does not support arbitrary operations other than function nor nested regions yet.

Comparing to the existing quant.const_fake_quant op, the min and max attributes
of this new op is for each channel of last dimension of the input.

For per channel fake quant attributes, the returned type should be
UniformQuantizedPerAxisType. Currently, this method isn't under test because we
haven't added the quant_ConstFakeQuantPerAxis op and the convert method.

Some compilers will try to auto-generate the destructor, instead of using the user provided destructor, when creating a default move constructor.

This allows for parallelizing across pipelines of multiple operation types. AdaptorPasses can now hold pass managers for multiple operation types and will dispatch based upon the operation being operated on.

This method parses an operation in its generic form, from the current parser
state. This is the symmetric of OpAsmPrinter::printGenericOp(). An immediate
use case is illustrated in the test dialect, where an operation wraps another
one in its region and makes use of a single-line pretty-print form.

This is done via a new set of instrumentation hooks runBeforePipeline/runAfterPipeline, that signal the lifetime of a pass pipeline on a specific operation type. These hooks also provide the parent thread of the pipeline, allowing for accurate merging of timers running on different threads.

This is the only example for overriding this interface in the repo, let's

This will allow clients to implement a different collection strategy on these

The current restrictions on dim/symbols require a top-level symbol for the conservative case of a non-affine region. This should be relaxed in the future.
