This commit adds a new frontend flag that applies debug path prefixing to the
paths serialized in swiftmodule files. This makes it possible to use swiftmodule
files that have been built on different machines by applying the inverse map
when debugging, in a similar fashion to source path prefixing.
The inverse mapping in LLDB will be handled in a follow up PR.
Second pass at #39138
Tests updated to handle windows path separators.
This reverts commit f5aa95b381.
This commit adds a function to remap the clang arguments passed
during compilation. This is intented to be shared across the
Swift compiler and LLDB to apply path remapping for debug info
paths.
Mangling can fail, usually because the Node structure has been built
incorrectly or because something isn't supported with the old remangler.
We shouldn't just terminate the program when that happens, particularly
if it happens because someone has passed bad data to the demangler.

Make sure that we add the appropriate rpaths so that the appropriate
_Concurrency back-deployment library can be picked up.
We don't need to update the Swift driver since it uses the C++ driver
as the source of truth to determine if the relevant rpath should be
added or not.
To allow us to start testing language changes tied to a future Swift 6 mode without actually *shipping* a Swift 6 mode to customers who might accidentally use it before it's ready.
This commit also adds parallel tests for a number of already existing (but untested) Swift 6 mode behaviors.

Introduce a second level of standard substitutions to the mangling,
all of the form `Sc<character>`, and use it to provide standard
substitutions for most of the _Concurrency types.
This is a precursor to rdar://78269642 and a good mangling-size
optimization in its own right.
This will allow teams writing access notes to use -Raccess-note=all-validate to check that their access notes are correct, or teams working around problems to use -Raccess-note=failures or -Raccess-note=none to suppress diagnostics.
