Controlled with a new flag '-direct-clang-cc1-module-build'
This will allow clients to formulate 'swift-frontend' invocations with fully-specified set of cc1 arguments (using '-Xcc -Xclang -Xcc <FLAG>') required for the PCM build, without having to go through the driver.

Originally protocols prefixed with 'some' keyword are considered an opaue return
type representation. In order to understand plain protocols, the GenericParamList
Request must understand how to build a generic parameter list using alternative
type representations: identifier and composition.
This includes:
- bumping the SWIFT_SYMBOLGRAPH_FORMAT_MINOR version
- introduction of the "swift.extension" symbol and "extensionTo" relationship
- adding support for ExtensionDecl to the Symbol class
- adding a "typeKind" field to the symbol's extension mixin which indicates what kind
of symbol was extended
- intoduction of the -emit-extension-block-symbols flag, which enables the behavior
outlined below
- adaptions to SymbolGraphASTWalker that ensure a swift.extension symbol is emitted
for each extension to a type that does not exist in the local symbol graph
- adaptions to SymbolGraph and SymbolGraphASTWalker that ensure member and conformance
relationships are correctly associated with the swift.extension symbol instead of
the original type declaration's (extended nominal's) symbol where applicable
- adaptions to SymbolGraphASTWalker that ensure swift.extension symbols are connected
to their respective extended nominal's symbol using an extensionTo relationship
Testing:
- adds SymbolGraph tests that test behavior only relevant in
-emit-extension-block-symbols mode
- adapts some SymbolGraph tests to additionally test similar behavior for
extensions to external types in -emit-extension-block-symbols mode
- adapts some SymbolGraph tests to (additionally or exclusively) test the
behavior with -emit-extension-block-symbols mode enabled
Bugfixes:
- fixes a bug where some conformsTo relationships implicated by the conformances
declared on an extension to an external type were not emitted
(see test/SymbolGraph/Relationships/ConformsTo/Indirect.swift)
Further changes:
- documents the strategy for naming and associating children declared in extensions
to typealiases (see test/SymbolGraph/Relationships/MemberOf/Typealias.swift,
test/SymbolGraph/Symbols/Names.swift)
Basic should not be allowed to link Parse, yet it was doing so
to allow Version to provide a constructor that would conveniently
parse a StringRef. This entrypoint also emitted diagnostics, so it
pulled in libAST.
Sink the version parser entrypoint down into Parse where it belongs
and point all the clients to the right place.
Trivial conflict caused by the line above the
`IGM.constructInitialFnAttributes` change in `lib/IRGen/GenDecl.cpp`
having an extra argument passed in rebranch (due to the new LLVM API).
This patch gets everything to the point of building the library, but it
doesn't run yet since I have missing symbols.
Unlike previous compatibility libraries and the concurrency
compatibility library, I'm organizing the headers a bit more. This is
because we're merging the two libraries into one. They share some common
header names, and while I could rename them for namespacing purposes,
it's easier to just use a directory structure for this.
The `include/Runtime` and corresponding `Runtime/` directories are for
backdeployed changes to the stdlib itself.
The `include/Concurrency` and corresponding `Concurrency/` directories
are for backdeployed changes to the concurrency runtimes.
Adds frontend option -enable-stack-protector to enable emission of a
stack protector.
Disabled by default.
When enabled enables LLVM's strong stack protection mode.

I am separating the concern of weakly linking symbols that are introduced at the deployment target from the concern of type checking this new type of potential unavailability.
Resolves rdar://97925900
Put pointers to class_ro_t referenced from generic class patterns in a section __swift_rodatas such that they are discoverable by the linker.
The linker can then make the method lists contained in the class_ro_t relative like it can for objective c class metadata from non-generic swift classes.

This was already enabled as part of `-enable-implicit-dynamic` but this
new flag allows turning on opaque type erasure all by itself whether or
not `dynamic` is added explicitly.

Introduce the `-enable-upcoming-feature X` command-line argument to
allow one to opt into features that will be enabled in an upcoming language
mode. Stage in several features this way (`ConciseMagicFile`,
`ForwardTrailingClosures`, `BareSlashRegexLiterals`).
