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.

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)"
}
}
```

Zero bit integer types are supported by IntegerType for consistency,
but the asmparser never got updated. Allow them to be parsed, as
required to fix CIRCT issue #316

This revision optimizes the parsing of hex strings by using the checked variant of llvm::fromHex, and adding a specialized method to Token for extracting hex strings. This leads a large decrease in compile time when parsing large hex constants (one example: 2.6 seconds -> 370 miliseconds)

Summary: At this point Parser has grown to be over 5000 lines and can be very difficult to navigate/update/etc. This commit splits Parser.cpp into several sub files focused on parsing specific types of entities; e.g., Attributes, Types, etc.

Summary:
While here, simplify the lexer a bit by eliminating the unneeded 'operator'
classification of certain sigils, they can just be treated as 'punctuation'.

Thus far IntegerType has been signless: a value of IntegerType does
not have a sign intrinsically and it's up to the specific operation
to decide how to interpret those bits. For example, std.addi does
two's complement arithmetic, and std.divis/std.diviu treats the first
bit as a sign.
This design choice was made some time ago when we did't have lots
of dialects and dialects were more rigid. Today we have much more
extensible infrastructure and different dialect may want different
modelling over integer signedness. So while we can say we want
signless integers in the standard dialect, we cannot dictate for
others. Requiring each dialect to model the signedness semantics
with another set of custom types is duplicating the functionality
everywhere, considering the fundamental role integer types play.
This CL extends the IntegerType with a signedness semantics bit.
This gives each dialect an option to opt in signedness semantics
if that's what they want and helps code sharing. The parser is
modified to recognize `si[1-9][0-9]*` and `ui[1-9][0-9]*` as
signed and unsigned integer types, respectively, leaving the
original `i[1-9][0-9]*` to continue to mean no indication over
signedness semantics. All existing dialects are not affected (yet)
as this is a feature to opt in.

The restriction that symbols can only have identifier names is arbitrary, and artificially limits the names that a symbol may have. This change adds support for parsing and printing symbols that don't fit in the 'bare-identifier' grammar by printing the reference in quotes, e.g. @"0_my_reference" can now be used as a symbol name.

This commit creates a static constexpr limit for the IntegerType
bitwidth and uses it. The check had to be moved because Token is
not aware of IR/Type and it was a sign the abstraction leaked:
bitwidth limit is not a property of the Token but of the IntegerType.
Added a positive and a negative test at the limit.

We don't need to C-escape any more, so don't. Also, change the expected escaping syntax to be the slightly noisier version that LLVM emits.

print floating point in a structured form that we know can round trip,
enumerate attributes in the visitor so we print affine mapping attributes
symbolically (the majority of the testcase updates).
We still have an issue where the hexadecimal floating point syntax is reparsed
as an integer, but that can evolve in subsequent patches.

This patch passes the raw, unescaped value through to the rest of the stack. Partial escaping is a total pain to deal with, so we either need to implement escaping properly (ideally using a third party library like absl, I don't think LLVM has one that can handle the proper gamut of escape codes) or don't escape. I chose the latter for this patch.

This is doing it in a suboptimal manner by recombining [integer period literal] into a string literal and parsing that via to_float.
