For various reasons, it can be useful/interesting to create builds of
Swift that minimize dependencies. Let's try to keep that working as long
as we can.
Extensions redeclare all generic parameters of their extended type to add their additional restrictions. There are two issues with this model for indexing:
- The generic paramter declarations of the extension are implicit so we wouldn't report them in the index. Any usage of the generic param in the extension references this implicit declaration so we don't include it in the index either.
- The implicit re-declarations have their own USRs so any usage of a generic parameter inside an extension would use a different USR than declaration of the param in the extended type.
To fix these issues, we replace the reference to the implicit generic parameter defined in the extension by a reference to the generic paramter defined in the extended type.
Various uses of `getPresumedLineAndColumnForLoc` were likely added when
that function was the very misleading name `getLineAndColumn`. Change
these to use `getLineAndColumnForBuffer` instead where appropriate, ie.
we want the underlying file rather than the location to display to the
user.
There were also some cases where the buffer identifier had been swapped
to use the display name instead, under the assumption that the presumed
location was needed. Updated those as well.
SingleRawComment: Lines are only used when merging comments, where the
original location is fine to use.
Index: Doesn't store the file set in #sourceLocation, so using the
presumed line would end up pointing to a location that makes no sense.
Editor functionality: Formatting and refactoring are on the current
file. Using the presumed location would result in incorrect
replacements.
`class` functions can be overridden in subclasses but did not have the
`Dynamic` role added to their calls. Also add the `ReceivedBy` relation
in the simple case of an open archetype, leaving the more complicated
general generic case for now.
The frontend supports this via new options -index-unit-output-path and
-index-unit-output-path-filelist that mirror -o and -output-filelist. These are
intended to allow sharing index data across builds in separate directories (so
different -o values) that are otherwise equivalent as far as the index data is
concerned (e.g. an ASAN build and a non-ASAN build) by supplying the same
-index-unit-output-path for both.
This change updates the driver to add these new options to the frontend
invocation 1) when a new "index-unit-output-path" entry is specified for one
or more input files in the -output-file-map json or 2) if -index-file is
specified, when a new -index-unit-output-path driver option is passed.

These new options mirror -o and -output-filelist and are used instead
of those options to supply the output file path(s) to record in the
index store. This is intended to allow sharing index data across
builds in separate directories that are otherwise equivalent as far
as the index data is concered (e.g. an ASAN build and a non-ASAN build)
by supplying the same -index-unit-output-path for both.

"Function builders" are being renamed to "result builders". Add the
corresponding `@resultBuilder` attribute, with `@_functionBuilder` as
an alias for it, Update test cases to use @resultBuilder.
This was happening in the error recovery path when parsing accessors
on a pattern binding declaration that does not bind any variables, eg
let _: Int { 0 }
Unlike \keypath expressions, only the property components of #keypath
expressions were being resolved, so index wouldn't pick up references for their
qualifying types.
Also fixes a code completion bug where it was reporting members from the Swift
rather than ObjC side of bridged types.

Build swift-frontend as the primary Swift binary, and have
swift/swiftc/etc. symlink over to it. This is a step toward allowing
swift-driver to replace the swift and swiftc binaries.
For DoubleCurryThunk cases it’s expecting an ApplyExpr directly within the
OpenExistentialExpr, but in some cases it contains an ErasureExpr (implicit
conversion) that wraps the ApplyExpr. This updates the method to look
through implicit conversions.

This change makes us treat it exactly as we do 'init'. We don't allow renaming the base name,
and don't fail if the basename doesn't match for calls.
Also:
- explicit init calls/references like `MyType.init(42)` are now reported with
'init' as a keywordBase range, rather than nothing.
- cursor info no longer reports rename as available on init/callAsFunction
calls without arguments, as there's nothing to rename in that case.
- Improved detection of when a referenced function is a call (rather than
reference) across syntactic rename, cursor-info, and indexing.

c-index-test sorts the units by their file name, which for the modules in
in this test is just [target-triple].swiftinterface-[hash-of-full-output-path]
and so changes depending on where it's run.
Several tests related to indexing system modules were taking a considerable
amount of time (100+ seconds in the worst case) indexing the standard library.
This adds a frontend option to skip it and updates those tests to pass it.
* Reference is marked "explicit", which may be unexpected - the reason
is that the *call* is explicit, so we want to find it with e.g. rename,
or looking up callers, even though the identifier callAsFunction is
implicit. This matches the behaviour of initializers.
* The source location is the same as the base name (e.g. in `add3(5)`,
it would be at `add3`), which matches the behaviour of initializers.

For code like
```
_ = type(of: x).A.self
```
the `A` type reference is written explicitely by the user, but the AST created using `TypeExpr::createImplicitHack` is hiding such a reference,
making the reference invisible to semantic functionality like 'rename'.

Rely on the `ls` behaviour of returning a non-zero if there is no
matching pattern. This should help make the test pass on Windows
and the other targets.
