This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
When serializing to bytecode, users can select the option to elide
resources from the bytecode file. This will instruct the bytecode writer
to serialize only the key and resource kind, while skipping
serialization of the data buffer. At parsing, the IR is built in memory
with valid (but empty) resource handlers.
Seprate registeration and CLI parsing from `MlirOptMain` to
`mlir::registrationAndParseCLIOptions` and a new `MlirOptMain` so that
external tools to drive `mlir-opt` can call these two new APIs to get CLI
option values before running `MlirOptMain`.
This commit adds the initial version of the mlir-query tool, which leverages the pre-existing matchers defined in mlir/include/mlir/IR/Matchers.h
The tool provides the following set of basic queries:
hasOpAttrName(string)
hasOpName(string)
isConstantOp()
isNegInfFloat()
isNegZeroFloat()
isNonZero()
isOne()
isOneFloat()
isPosInfFloat()
isPosZeroFloat()
isZero()
isZeroFloat()

This commit enables the expression of negated native constraints in PDLL:
If a constraint is prefixed with "not" it is parsed as a negated constraint and hence the attribute `isNegated` of the emitted `pdl.apply_native_constraint` operation is set to `true`.
In first instance this is only supported for the calling of external native C++ constraints and generation of PDL patterns.
Previously, negating a native constraint would have been handled by creating an additional native call, e.g.
```PDLL
Constraint checkA(input: Attr);
Constarint checkNotA(input: Attr);
```
or by including an explicit additional operand for negation, e.g.
`Constraint checkA(input: Attr, negated: Attr);`
With this a constraint can simply be negated by prefixing it with `not`. e.g.
```PDLL
Constraint simpleConstraint(op: Op);
Pattern example {
let inputOp = op<test.bar>() ->(type: Type);
let root = op<test.foo>(inputOp.0) -> ();
not simpleConstraint(inputOp);
simpleConstraint(root);
erase root;
}
```

Functions are always callable operations and thus every operation
implementing the `FunctionOpInterface` also implements the
`CallableOpInterface`. The only exception was the FuncOp in the toy
example. To make implementation of the `FunctionOpInterface` easier,
this commit lets `FunctionOpInterface` inherit from
`CallableOpInterface` and merges some of their methods. More precisely,
the `CallableOpInterface` has methods to get the argument and result
attributes and a method to get the result types of the callable region.
These methods are always implemented the same way as their analogues in
`FunctionOpInterface` and thus this commit moves all the argument and
result attribute handling methods to the callable interface as well as
the methods to get the argument and result types. The
`FuntionOpInterface` then does not have to declare them as well, but
just inherits them from the `CallableOpInterface`.
Adding the inheritance relation also required to move the
`FunctionOpInterface` from the IR directory to the Interfaces directory
since IR should not depend on Interfaces.

In preparation for removing the `#include "llvm/ADT/StringExtras.h"`
from the header to source file of `llvm/Support/Error.h`, first add in
all the missing includes that were previously included transitively
through this header.
This class has been causing me no end of grief for a long time, and the way it is used by mlir-tblgen is technically an ODR violation in certain situations.
Due to the way that the build is layered, it is important that the MLIR tablegen libraries only depend on the LLVM tablegen libraries, not on anything else (like MLIRSupport). It has to be this way because these libraries/binaries are special and must pre-exist the full shared libraries. Therefore, the dependency chain must be clean (and static).
At some point, someone pulled out a separate build target for just IndendedOstream in an attempt to satisfy the constraint. But because it is weird in different ways, this target was never installed properly as part of distributions, etc -- this causes problems for downstreams seeking to build a tblggen binary that doesn't itself have ODR/shared library problems.
I was attempting to fix the distribution stuff but just opted to collapse this into a header-only library and not try to solve this with build layering. I think this is the safest and the least bad thing for such a dep. This also makes for a clean comment that actually explains the constraint (which I was having trouble verbalizing with the weird subset dependency).

Implementation:
This first patch was created with the following steps. The intention is
to only do automated changes at first, so I waste less time if it's
reverted, and so the first mass change is more clear as an example to
other teams that will need to follow similar steps.

3. Delete .inc files that were also modified, so the next build rebuilds

4. Some changes have been deleted for the following reasons:
- Some files had a variable also named cast
- Some files had not included a header file that defines the cast
functions
- Some files are definitions of the classes that have the casting
methods, so the code still refers to the method instead of the
function without adding a prefix or removing the method declaration
at the same time.

When tooling out there produces a reproducer that is archived, the first thing
a user is likely to expect is to process this as they do with any MLIR file.
However https://reviews.llvm.org/D126447 changed the behavior of mlir-opt to
eliminate the `--run-reproducer` option and instead automatically run it when
present in the input file. This creates a discrepancy in how mlir-opt behaves
when fed with an input file, and is surprising for users.
The explicit passing of `--run-reproducer` to express user-intent seems more
in line with what is expected from `mlir-opt`.
