This is for the 'freestanding' build to stop assuming the platform has argc/argv.
- Introduce a new sub-library, libswiftCommandLineSupport.a
- Move stubs/CommandLine.cpp into this library
- Conditionally embed it into libswiftCore
- Conditionally embed it into libswiftPrivateLibcExtras if not in libswiftCore to support testing
- Add SWIFT_STDLIB_HAS_COMMANDLINE CMake (and build-script) flag
Certain traps can't be supported on WASI, such as expectations for crashes, `setjmp` use, dynamic linking, multi-threading etc. These tests are marked as `UNSUPPORTED` when targeting Wasm/WASI.
Welp, the bogus precondition that was fixed in https://github.com/apple/swift/pull/37960 indeed doesn't entirely deploy back to previous OSes.
This makes sense -- bridging is generally not specialized.

When we fall back to loading an arm64e module interface during an arm64 build, we want to compile it for the arm64 target so that it is fully compatible with the module that will load it, even though the flags in the file specify the arm64e target. Rewrite the sub-invocation's TargetTriple property in this specific situation. If the two targets differ by more than just the sub-architecture, we will continue to respect the -target flag in the file.
Fixes <rdar://83056545>.
I wasn't aware that arm64e was a thing in open-source, but these two
tests are failing on Apple Silicon both on the main branch and on the
rebranch branch, so I'm disabling it for now.
The failing tests are:
- ModuleInterface/arm64e-fallback.swift
- stdlib/Reflection_objc.swift
- Increase impact of a generic pointer-to-pointer mismatch fix to
match that of a contextual type failure. This allows more specific
fixes to take precedence.
- De-prioritize generic argument mismatch fix when both types are
pointers. This allows pointer-to-pointer conversion produce a
more specific fix.
- De-prioritize fixes that involve `Builtin.RawPointer` or `OpaquePointer`
in parameter positions. This helps to produce better diagnostics
for argument mismatches during pointer initialization e.g.
`UnsafeRawPointer(<pointer>)`.
The other instances had been disabled in commit 5236224eb1.
FileCheck was recently updated so that it complains about undefined
variables, which is why no one noticed until now. storage3 wasn't
defined because the place where it got defined was disabled. Disabling
that instance now.
These tests require a newer runtime and fail on older OSes:
test/Concurrency/Runtime/actor_detach.swift
test/Concurrency/Runtime/actor_init.swift
test/Interpreter/rdar80847020.swift
test/stdlib/Reflection_objc.swift
