Leave the old flag in as an alias to the new flag, for transition
purposes. Also go ahead and remove the long-deprecated and unused
`emit-interface-path`.

Makes it easier to test the caching behavior, and may also be useful
for "prebuilding" swiftinterfaces in the future, or having the Driver
kick off a bunch of separate builds as proper tasks.
We already have something called "module interfaces" -- it's the
generated interface view that you can see in Xcode, the interface
that's meant for developers using a library. Of course, that's also a
textual format. To reduce confusion, rename the new module stability
feature to "parseable [module] interfaces".
Textual module interfaces don't actually depend on SILGen, so we
shouldn't need to run SILGen (or serialize an entire binary module) if
we're just trying to emit a textual interface. On the other hand, if
we /are/ going to run SILGen and then SIL diagnostics, we shouldn't
delay those diagnostics by spending time emitting a textual interface,
or for that matter a TBD file.
Using this, update all the ModuleInterface tests that use
`-emit-module -o /dev/null` to use `-typecheck` instead, except for
those using `-merge-modules`.
This silences the instances of the warning from Visual Studio about not all
codepaths returning a value. This makes the output more readable and less
likely to lose useful warnings. NFC.
Continuing work from #18344, be more conservative about when we load
SwiftOnoneSupport. Specifically, -emit-silgen and -emit-sibgen, despite
not going through the SIL Optimizer, may silently introduce dependencies
on SwiftOnoneSupport.
Because we want to support the ability to posthumously compile SILGen
and SIBGen'd files with these implicit dependencies, and because SIL
is not yet capable of expressing the dependency itself, we must always
assume we need to load SwiftOnoneSupport.
SwiftOnoneSupport is an implicit dependency of no-opt builds that is usually
only loaded when frontend actions that emit optimization-sensitive outputs are
run.
Force the implicit dependency to be explicit when -track-system-dependencies is
used in concert with frontend actions that requires SIL passes be run.
...instead of sometimes hardcoding them and sometimes using Strings.h.
The exceptions are the libraries that sit below Frontend; these can
continue using strings.
...but don't hook it up to anything yet.
This is the very very start of the module stability / textual
interfaces feature described at
https://forums.swift.org/t/plan-for-module-stability/14551/
For now I've just made it a frontend option (not a driver option),
which is good enough for testing.
Introduces the -name-bind frontend action that is intended as an intermediary between the parse-only actions and a full typechecking pass. In this phase, module imports will be validated and resolved, making it possible to emit full make-style dependencies files among other things.
Note that all information available to a parse-only pass is available to name binding, but because it does not continue-on to typecheck input files, full semantic information is not.
Parse-only invocations do not support the proper creation of dependency files or reference dependency files because they have not yet run name binding. Ban these invocations by diagnostic and add a new diagnostic specifically for reference dependencies.
- Outlaw duplicate input files, fix driver, fix tests, and add test.
- Reflect that no buffer is present without a (possibly pseudo) named file.
- Reflect fact that every input has a (possible pseudo) name.
- Break up CompilerInstance::setup.
Don't bail on dups.
- Moved getOutputFilenamesFromCommandLineOrFilelist & readOutputFileLIst to better places in the file.
- Capitalization changes.
- Make actionIsImmediate static.
- Add braces around sections of CompilerInstance::setup to clarify scopes of local variables.
Unify actionHasOutput w/ doesActionProduceOutput & correct both.
Do not set an output filename if there is no output.
Add test to ensure no output is created in immediate mode.
