Currently, when we jump-to-definition for decls that are macro-expanded
from Clang imported decls (e.g., safe overloads generated by
@_SwiftifyImport), setLocationInfo() emits a bongus location pointing to
a generated buffer, leading the IDE to try to jump to a file that does
not exist.
The root cause here is that setLocationInfo() calls getOriginalRange()
(earlier, getOriginalLocation()), which was not written to account for
such cases where a macro is generated from another generated buffer
whose kind is 'AttributeFromClang'.
This patch fixes setLocationInfo() with some refactoring:
- getOriginalRange() is inlined into setLocationInfo(), so that the
generated buffer-handling logic is localized to that function. This
includes how it handles buffers generated for ReplacedFunctionBody.
- getOriginalLocation() is used in a couple of other places that only
care about macros expanded from the same buffer (so other generated
buffers not not relevant). This "macro-chasing" logic is simplified
and moved from ModuleDecl::getOriginalRange() to a free-standing
function, getMacroUnexpandedRange() (there is no reason for it to be
a method of ModuleDecl).
- GeneratedSourceInfo now carries an extra ClangNode field, which is
populated by getClangSwiftAttrSourceFile() when constructing
a generated buffer for an 'AttributeFromClang'. This could probably
be union'ed with one or more of the other fields in the future.

(cherry picked from commit 44aba1382d)
Make `getOriginalLocation` work with source ranges, and adjust the
cursor info logic to map the range into the original buffer. This
fixes the case where we were using bogus range lengths for macro
expansion decls.

We need this option for `collectVariableType` (aka inlay type hints) but since I’m at it, I’m adding an option to disable the implicit request cancellation for all requests that have it since we don’t want it in LSP at all.
Prerequisite to fixing https://github.com/swiftlang/sourcekit-lsp/issues/2021 / rdar://145871554, need to adopt this option in SourceKit-LSP.
If a module has the same `public-module-name` as the module being
generated and its import is exported, merge it into the same generated
interface.
Fix various always-imported modules from being printed while here and
update all the tests that checked for them.

When a function declaration has a body, its source range ends at the
closing curly brace, so it includes the `throws(E)`. However, a
protocol requirement doesn't have a body, and due to an oversight,
getSourceRange() was never updated to include the extra tokens
that appear after `throws` when the function declares a thrown
error type. As a result, unqualified lookup would fail to find a
generic parameter type, if that happened to be the thrown type.
Fixes rdar://problem/143950572.
Resolving cursor info is async and can occur after the request has been
deleted, make sure to take a copy of the `USR` (which is part of that
request).
Resolves rdar://137320169.
The "buffer ID" in a SourceFile, which is used to find the source file's
contents in the SourceManager, has always been optional. However, the
effectively every SourceFile actually does have a buffer ID, and the
vast majority of accesses to this information dereference the optional
without checking.
Update the handful of call sites that provided `nullopt` as the buffer
ID to provide a proper buffer instead. These were mostly unit tests
and testing programs, with a few places that passed a never-empty
optional through to the SourceFile constructor.
Then, remove optionality from the representation and accessors. It is
now the case that every SourceFile has a buffer ID, simplying a bunch
of code.
We ran SwiftParser in `handlePrimaryAST` for related identifiers. That function is called on a dispatch queue with reduced stack size and could cause the parser to stack overflow if the program is very nested.
Run `handlePrimaryAST` on a deep stack for this request to fix the issue.

This has two benefits:
1. We can now report ambiguous variable types
2. We are more robust in the generation of results for declarations inside closures. If the closure has an error, we won’t apply the solution to the AST and thus any cursor info that tried to get types out of the AST would fail.

LLVM is presumably moving towards `std::string_view` -
`StringRef::startswith` is deprecated on tip. `SmallString::startswith`
was just renamed there (maybe with some small deprecation inbetween, but
if so, we've missed it).
The `SmallString::startswith` references were moved to
`.str().starts_with()`, rather than adding the `starts_with` on
`stable/20230725` as we only had a few of them. Open to switching that
over if anyone feels strongly though.
* Record each IfConfig clause location info in SourceFile
* Update SILProfiler to handle them
* Update SwiftLangSupport::findActiveRegionsInFile() to use the recorded
regions instead of walking into AST to find #if regions

SourceKit-LSP currently parses the XML comment to generate Markdown again but round-tripping a (probably markdown) doc comment to XML to Markdown is lossy in many cases and unnecessary work. Include the comment as it is spelled in source in the cursor info response so that sourcekit-lsp can display it.

Performing a related identifiers request on `self` returns an empty result because `self` is not an identifier. We thus can’t retrieve the first location to compute the old name.

If the file didn’t exist on disk, `fileSystem->getRealPath` returns an empty string, which means we can’t find the `InputBuffer` and thsu won’t run solver-based cursor info. There’s no reason to realpath `PrimaryInputPath`, `getMemoryBuffer` already does that.

While we don't want to return non-editable base names for Edit-All-In-Scope, we do want to return them if the related identifiers response is used as the input for find-syntactic-rename-ranges.
This allows building sourcekitd and swift-refactor with `SWIFT_BUILD_SWIFT_SYNTAX=NO`. In these builds, the `relatedidents` and `find-syntactic-rename-ranges` requests will always return an error.
We should (and do) have one new name for the entire rename operation, not a separate new name for different positions at which the renamed symbol occurs.
We need this request for semantic highlighting in LSP. Previously, we were getting the semantic tokens using a 0,0 edit after a document update notification but that will no longer be possible if we open the documents in syntactic only mode.
