- Fix typo
- Document Offset and Length semantics in collectVariableTypes
This can be used to measure how many instructions a request executes by retrieving the number of instructions executed since the process’s start before and after executing the request.
We were only keeping track of `RawSyntax` node IDs to incrementally transfer a syntax tree via JSON. However, AFAICT the incremental JSON transfer option has been superceeded by `SyntaxParseActions`, which are more efficient.
So, let’s clean up and remove the `RawSyntax` node ID and JSON incremental transfer option.
In places that still need a notion of `RawSyntax` identity (like determining the reused syntax regions), use the `RawSyntax`’s pointer instead of the manually created ID.
In `incr_transfer_round_trip.py` always use the code path that uses the `SyntaxParseActions` and remove the transitional code that was still using the incremental JSON transfer but was never called.
Cursor info for a constructor would previously give the cursor info for
the containing type only. It now also adds cursor info for the
constructor itself in a "secondary_symbols" field.
Refactor `passCursorInfoForDecl` to use a single allocator rather than
keeping track of positions in a buffer and assigning everything at the
end of the function.
Refactor the various available refactoring gathering functions to take a
SmallVectorImpl and to not copy strings where they don't need to.

Adds two new fields to the cursor info response:
1. is_dynamic: whether a call is dynamic
2. receivers: receivers of the call (USRs)
Users of the CursorInfo request can use "is_dynamic" to decide whether
to lookup overrides or not, and then the "receivers" as the starting
point of the lookup.

When the SymbolGraph json is requested via (key.retrieve_symbol_graph: 1) this adds
a new field in the response that lists all the parent contexts of the symbol under
the cursor with their symbol graph kind and name, and their USR:
key.parent_contexts: [
{
key.kind: "swift.struct",
key.name: "Parent",
key.usr: "s:27cursor_symbol_graph_parents6ParentV"
},
...
]
}

It was originally designed for faster trasmission of syntax trees from
C++ to SwiftSyntax, but superceded by the CLibParseActions. There's no
deserializer for it anymore, so let's just remove it.
Consolidate ThrowsKeyword, RethrowsKeyword, and AsyncKeyword to
EffectsSpecifierKeyword.
Abolish 'key.throwsoffset' and 'key.throwslength' as they aren't used.
Adds a new 'key.retrieve_symbol_graph' option to the request. When set to 1 it
includes the JSON for a SymbolGraph containing a single node for the symbol at
the requested position.
This also extends the SymbolGraph library with a new entry point to get a graph
for a single symbol, and to additionally support type substitution to match the
existing CursorInfo behavior (e.g. so that when invoked on `first` in
`Array<Int>().first`, the type is given as `Int?` rather than `Element?`).

Check if dependencies are modified since the last checking.
Dependencies:
- Other source files in the current module
- Dependent files collected by the dependency tracker
When:
- If the last dependency check was over N (defaults to 5) seconds ago
Invalidate if:
- The dependency file is missing
- The modification time of the dependecy is greater than the last check
- If the modification time is zero, compare the content using the file
system from the previous completion and the current completion

SwiftSourceInfo files provide source location information for decls coming from
loaded modules. For most IDE use cases it either has an undesirable impact on
performance with no benefit (code completion), results in stale locations being
used instead of more up-to-date indexer locations (cursor info), or has no
observable effect (live diagnostics, which are filtered to just those with a
location in the primary file).
For non-IDE clients of SourceKit though, cursor info providing declaration
locations for symbols from other modules is useful, so add a global
configuration option (and a new request to set it) to control whether
.swiftsourceinfo files are loaded or not based on use case (they are loaded by
default).
This custom buffer encapsulates the memory layout details of the response
for the expression type request. From the client side, each expression type
is represented as a tuple of {expr_offset, expr_length, printed_type}.

This request collects the types of all expressions in a source file after type checking.
To fulfill this task, the client must provide the path to the Swift source file under
type checking and the necessary compiler arguments to help resolve all dependencies.
Request:
{
<key.request>: (UID) <source.request.expression.type>,
<key.sourcefile>: (string) // Absolute path to the file.
<key.compilerargs>: [string*] // Array of zero or more strings for the compiler arguments,
// e.g ["-sdk", "/path/to/sdk"]. If key.sourcefile is provided,
// these must include the path to that file.
}
Response:
{
<key.printedtypebuffer>: (string) // A text buffer where all expression types are printed to.
<key.expression_type_list>: (array) [expr-type-info*] // A list of expression and type
}
expr-type-info ::=
{
<key.expression_offset>: (int64) // Offset of an expression in the source file
<key.expression_length>: (int64) // Length of an expression in the source file
<key.type_offset>: (int64) // Offset of the printed type of the expression in the printed type buffer
<key.type_length>: (int64) // Length of the printed type of the expression in the printed type buffer
}

`source.request.conformingmethods` is a new SourceKit request which
receives a source position and a list of protocol namses, returns a list
of methods whose return type conforms to the requested protocols.
rdar://problem/44699573
This is a new SourceKit request which receives a position in the source
file, returns possible expected types and their members which can be
referenced by "implicit member expression" syntax.
