In Python 3, subprocess output is read as binary data by default, which isn’t what we want.
Instead of reading process output as byte strings, then manually decoding them into strings, simply pass `text=True` to functions in the `subprocess` module, so that we get properly decoded strings right out the box.
This fixes places that forget to do the decoding step — most especially, the `update-checkout` script. That script prints Git output as byte strings, which leads to unreadable results.
Additionally, in shell.run, use the same pipe for capturing both stdout and stderr. The distinction is pretty pointless in this use case; however, keeping the two channels separate means that we lose the original ordering of printed messages, which does matter.
Internal configurations targeting Darwin employ ThinLTO to
improve compiler performance, however using it on all executable
causes build time to increase with no matching benefit.
To reduce build times in such configurations, we allow some
ancillary targets to opt out of LLVM IR optimizations when linking
ThinLTO with ld64 (e.g. tools used for bootstrapping or debugging the
Swift compiler) -- this behaviour is opt in through a new flag
`--swift-tools-ld64-lto-codegen-only-for-supporting-targets`.

This commit or the earlier commit this commit is based on (#40531) broke the
incremental bot.
In python3, 'filter' returns an interable which doesn't support using
'len()'. This switches to a list comprehension, so that we can check the
length of 'enabled_pipeline'.
This is required to move build-script to Python3.
- Checkout apple/swift-experimental-string-processing using a tag.
- Build `_MatchingEngine` as part of libswift (`ExperimentalRegex`) using sources from the package.
- Parse regex literals using the parser from `_MatchingEngine`.
- Build both `_MatchingEngine` and `_StringProcessing` as part of core libs using sources from the package.
- Use `Regex<DynamicCaptures>` as the default regex type until we finalize apple/swift-experimental-string-processing#68.
* add an option to add freestanding to the Darwin platform, so that
to get expected compile behaviours (e.g. setting the install name)
* rework testing configuration to relax assumptions about freestanding
* add a preset to test such configuration (at least for PR testing)

To that end, move the --cross-compile-deps-path flag from build-script-impl to a
publicly documented build-script flag and use it for build-script products'
library dependencies too. Generate a SPM destination JSON file that can be used
both for cross-compiling these build-script products and by users for their own
Swift packages.
Also, add a native_toolchain_path() method, that uses a prebuilt toolchain if
available, and pass an install prefix in to swift-driver and sourcekit-lsp.

These modules are part of the experimental declarative string processing feature. If accepted to the Standard Library, _StringProcessing will be available via implicit import just like _Concurrency, though _MatchingEngine will still be hidden as an implementation detail.
`_MatchingEngine` will contain the general-purpose pattern matching engine ISA, bytecode, and executor. `_StringProcessing` will contain regular expression and pattern matching APIs whose implementation depends on the matching engine..
Also consolidates frontend flag `-enable-experimental-regex` as `-enable-experimental-string-processing`.

The latest Long Term Support NDK finally removed binutils, including the bfd/gold
linkers and libgcc. This simplifies our Android support, including making lld the
default linker for Android. Disable three reflection tests that now fail, likely
related to issues with swift-reflection-dump and switching to lld.

Also, add the libatomic dependency for Android armv7, just as on linux.
