With the local refactoring being removed, all production refactoring paths return a set of ranges to rename and don’t apply edits to the file. Thus, the `syntactic-rename` action also doesn’t make sense anymore.
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.
Previously we would only enable by default when
`parseArgs` was called. However this wouldn't
enable it for clients such as LLDB, who provide
their own invocation. Switch the default to `true`
in the `LangOptions`, and remove some redundant
uses of `-enable-experimental-string-processing`.
The frontend flag remains, as it may be useful to
disable.

Update to have a single refactoring collection method for cursor
refactorings and another for ranges. The various functions were only
needed because of the extra availability information on renames, so just
give that to all refactorings.
This adds a new `primary_file` key, which defaults to `sourcefile`. For
nested expansions, `primary_file` should be set to the containing file
and `sourcefile` to the name of the macro expansion buffer.
`getValue` -> `value`
`getValueOr` -> `value_or`
`hasValue` -> `has_value`
`map` -> `transform`
The old API will be deprecated in the rebranch.
To avoid merge conflicts, use the new API already in the main branch.

IDE/Refactoring had dependencies to libswiftIndex, but libswiftIndex
also depends on libswiftIDE (SourceEntityWalker, etc.)
To break libswiftIndex <-> libswiftIDE dependency cycle, move
"refactoring" related files to a new library 'libswiftRefactoring'

With the change to include `SmallVector.h` directly in `LLVM.h` rather
than forward declaring in the only case it matters (ie. Clang <= 5),
these fixes are no longer needed. Since defaulted version is preferred
when there's no better choice (which is presumably the case if that's
how they were originally added), use it instead. Some uses were instead
changed to add `llvm::` so remove that too.
Instead of checking that the stdlib can be loaded in a variety of places, check it when setting up the compiler instance. This required a couple more checks to avoid loading the stdlib in cases where it’s not needed.
To be able to differentiate stdlib loading failures from other setup errors, make `CompilerInstance::setup` return an error message on failure via an inout parameter. Consume that error on the call side, replacing a previous, more generic error message, adding error handling where appropriate or ignoring the error message, depending on the context.
These modules are part of the experimental declarative string processing feature. If accepted to the Standard Library, _StringProcessing will be available via implicit import just like _Concurrency, though _MatchingEngine will still be hidden as an implementation detail.
`_MatchingEngine` will contain the general-purpose pattern matching engine ISA, bytecode, and executor. `_StringProcessing` will contain regular expression and pattern matching APIs whose implementation depends on the matching engine..
Also consolidates frontend flag `-enable-experimental-regex` as `-enable-experimental-string-processing`.

This lets one customize in the compiler invocation where the compiler looks for
the stdlib. This is necessary if the toolchain is not using a stdlib installed
with it.
When a range is a single expression/statement/decl or part of
expression, also return cursor based refactorings for the start of the
range.
This is a stop gap until the available refactorings are properly fixed
to be more lenient in general - the current fix is a little odd as eg.
if all of `foo.bar()` is selected, rename will be returned as an
available refactoring for `foo`. Still an improvement over completely
missing cursor based refactorings, however.

`%build-clang-importer-objc-overlays` builds the
overlays for the current target rather than the
host, so update the `%refactor` invocations to
take the target as an argument.

`ClangFileRewriterHelper` only outputs the rewritten buffer when it's
destroyed, but the consumers were never being freed. Cleanup the
lifetime management of the stream and consumers so that they're properly
destroyed.
Rename `DuplicatingSourceEditConsumer` to
`BroadcastingSourceEditConsumer` to better describe its purpose.
This allows an async alternative function to be
created that forwards onto the user's completion
handler function through the use of
`withCheckedContinuation`/`withCheckedThrowingContinuation`.

When adding an async alternative, add the @completionHandlerAsync
attribute to the sync function. Check for this attribute in addition to
the name check, ie. convert a call if the callee has either
@completionHandlerAsync or a name that is completion-handler-like name.
The addition of the attribute is currently gated behind the experimental
concurrency flag.

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 three refactorings intended to help users migrate their existing
code to use the new async language features:
1. Convert call to use async alternative
2. Convert function to async
3. Add async alternative function
A function is considered to have an async alternative if it has a void
return type and has a void returning closure as its last parameter. A
method to explicitly mark functions as having an async alternative may
be added to make this more accurate in the future (required for eg.
a warning about a call to the non-async version of a function in an
async context).
(1) converts a call to use the new `await` async language syntax. If the
async alternative throws, it will also add `try`. The closure itself is
hoisted out of the call, see the comments on
`AsyncConversionStringBuilder` for specifics.
(2) converts a whole function to `async`, using (1) to convert any calls
in the function to their async alternatives. (3) is similar to (2), but
instead *adds* a function and replaces calls to its
completion/handler/callback closure parameter with `return` or `throws`.

Current modes are:
1. output the whole rewritten buffer, with RUN and CHECK lines removed
2. output each replacement in JSON
To make each refactoring (rather than the whole file) easier to test,
add a plain text output option that can be easily checked with
FileCheck.
Most clients were only using it to populate the
main module with files, which is now done by
`getMainModule`. Instead, they can now just rely
on parsing happening lazily.
Lift the `DisablePoundIfEvaluation` parsing option
into `LangOptions` to subsume the need for the
`EvaluateConditionals` parameter, and sink the
computation of `CanDelayBodies` down into
`createSourceFileForMainModule`.
This patch achieves this by updating indexing to reporting the position of
`foo` in occurrences of `$foo` as an occurrence of the `foo` symbol, so
that renames initiated on occurrences of the `foo` symbol will also result
in occurrences of the `$foo` symbol being updated correctly. This also means
find-references on foo will show places where $foo is used.
Making rename work in the other direction (invoking rename on $foo upating foo
occurrences too) is still todo.
