ed2fb1736a [mlir:LSP] Add support for MLIR code completions
This commit adds code completion results to the MLIR LSP using
a new code completion context in the MLIR parser. This commit
adds initial completion for dialect, operation, SSA value, and
block names.

3c043ab007 [MLIR][Affine] Allow <= in IntegerSet constraints
This patch extends the affine parser to allow affine constraints with `<=`.
This is useful in writing unittests for Presburger library and test in general.

The internal storage and printing of IntegerSet is still in the original format.

d71a8bb157 [MLIR][Affine] Allow affine-expr on RHS in IntegerSet
Currently, the parser for IntegerSet, only allows constraints like:

```
affine-constraint ::= affine-expr `>=` `0`
                    | affine-expr `==` `0`
```

This form is sometimes unreadable and painful to use when writing unittests
for Presburger library and tests in general.

This patch extends the parser to allow affine constraints with affine-expr on
the RHS:

```
affine-constraint ::= affine-expr `>=` `affine-expr`
                    | affine-expr `==` `affine-expr`
```

The internal storage and printing of IntegerSet is still in the original format.

ea488bd6e1 [mlir] Allow for attaching external resources to .mlir files
This commit enables support for providing and processing external
resources within MLIR assembly formats. This is a mechanism with which
dialects, and external clients, may attach additional information when
printing IR without that information being encoded in the IR itself.
External resources are not uniqued within the MLIR context, are not
attached directly to any operation, and are solely intended to live and be
processed outside of the immediate IR. There are many potential uses of this
functionality, for example MLIR's pass crash reproducer could utilize this to
attach the pass resource executing when a crash occurs. Other types of
uses may be embedding large amounts of binary data, such as weights in ML
applications, that shouldn't be copied directly into the MLIR context, but
need to be kept adjacent to the IR.

External resources are encoded using a key-value pair nested within a
dictionary anchored by name either on a dialect, or an externally registered
entity. The key is an identifier used to disambiguate the data. The value
may be stored in various limited forms, but general encodings use a string
(human readable) or blob format (binary). Within the textual format, an
example may be of the form:

```mlir
{-#
  // The `dialect_resources` section within the file-level metadata
  // dictionary is used to contain any dialect resource entries.
  dialect_resources: {
    // Here is a dictionary anchored on "foo_dialect", which is a dialect
    // namespace.
    foo_dialect: {
      // `some_dialect_resource` is a key to be interpreted by the dialect,
      // and used to initialize/configure/etc.
      some_dialect_resource: "Some important resource value"
    }
  },
  // The `external_resources` section within the file-level metadata
  // dictionary is used to contain any non-dialect resource entries.
  external_resources: {
    // Here is a dictionary anchored on "mlir_reproducer", which is an
    // external entity representing MLIR's crash reproducer functionality.
    mlir_reproducer: {
      // `pipeline` is an entry that holds a crash reproducer pipeline
      // resource.
      pipeline: "func.func(canonicalize,cse)"
    }
  }
```

aab7e2fa05 [MLIR][Parser] Fix AffineParser colliding bare identifiers with primitive types
The parser currently can't parse bare identifiers like 'i0' in affine
maps and sets, and similarly ids like f16/f32. But these bare ids are
part of the grammar - although they are primitive types.

```
error: expected bare identifier
set = affine_set<(i0, i1) : ()>
                   ^
```

This patch allows the parser for AffineMap/IntegerSet to parse bare
identifiers as defined by the grammer.

6841e6afba [mlir] support max/min lower/upper bounds in affine.parallel
This enables to express more complex parallel loops in the affine framework,
for example, in cases of tiling by sizes not dividing loop trip counts perfectly
or inner wavefront parallelism, among others. One can't use affine.max/min
and supply values to the nested loop bounds since the results of such
affine.max/min operations aren't valid symbols. Making them valid symbols
isn't an option since they would introduce selection trees into memref
subscript arithmetic as an unintended and undesired consequence. Also
add support for converting such loops to SCF. Drop some API that isn't used in
the core repo from AffineParallelOp since its semantics becomes ambiguous in
presence of max/min bounds. Loop normalization is currently unavailable for
such loops.
