Using newer targets can lead to build failures, see

This has no effect currently, it is meant to support the switch
to `LLVM_ENABLE_RUNTIMES` to build compiler-rt -- #58465

Make libSyntax depend on swift-syntax: the new home for all
of this infrastructure. This greatly simplifies the addition and
amending of syntax nodes as only the swift-syntax paired with a
swift checkout will need to be changed. This is in contrast to
the existing build flow where a paired PR to both repos must be
made to change anything here.
Note that a paired PR may still be required if the legacy parser
needs to be adjusted in response to syntax nodes changing, but I
anticipate this to be a much more infrequent event now that
the C++ end of libSyntax is deprecated.
With a properly prepared sysroot and toolchain file, these changes permit
cross-compilation of Swift as well as LLVM, CMark, and Dispatch (picking,
as usual, apple/swift-corelibs-libdispatch#556) from a Linux host
generating OpenBSD binaries.
The toolchain file must be specified as an environment variable to
`build-script` and discussion on how to properly set up the sysroot and
toolchain file will be handled later.
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).
These are better done via the SwiftConfigureSDK mechanism rather than
how I was doing them previously. Additionally, I've changed the way
that the swift-threading-package option works. In addition to
specifying just a single package name, you can specify it as a CMake
list (i.e. separate by semicolons) of colon-separated `sdk:package`
pairs, e.g. `osx:darwin;linux:pthreads`. You can also override it
for all SDKs and then specify for a given SDK; specifications for a
particular SDK take precedence over the global override. For instance
`pthreads;osx:darwin` says to use `pthreads` except on the OS X SDK
where we should use `darwin`.
Moved all the threading code to one place. Added explicit support for
Darwin, Linux, Pthreads, C11 threads and Win32 threads, including new
implementations of Once for Linux, Pthreads, C11 and Win32.

SWIFT_STDLIB_SINGLE_THREADED_RUNTIME is too much of a blunt instrument here.
It covers both the Concurrency runtime and the rest of the runtime, but we'd
like to be able to have e.g. a single-threaded Concurrency runtime while
the rest of the runtime is still thread safe (for instance).
So: rename it to SWIFT_STDLIB_SINGLE_THREADED_CONCURRENCY and make it just
control the Concurrency runtime, then add a SWIFT_STDLIB_THREADING_PACKAGE
setting at the CMake/build-script level, which defines
SWIFT_STDLIB_THREADING_xxx where xxx depends on the chosen threading package.
This is especially useful on systems where there may be a choice of threading
package that you could use.

Currently, SwiftCompilerSources' inclusion of the regex parser depends on CMake flag `SWIFT_ENABLE_EXPERIMENTAL_STRING_PROCESSING`. However, in some scenarios we want to build the regex parser as part of the compiler _without_ building the runtime modules. This patch makes building the regex parser the default regardless of `SWIFT_ENABLE_EXPERIMENTAL_STRING_PROCESSING`. Only when the build environment is missing the string processing repo, we skip building the regex parser by setting `SWIFT_BUILD_REGEX_PARSER_IN_COMPILER` to false.
This patch adds a zlib and static-zlib build product, respectively
producing a dynamic and static zlib library. This is a dependency of
building Foundation.
Crash reporter integration was only enabled for iOS. Enable it for
any Darwin platform, but disable it for the minimal build.
Also fix up a couple of issues that popped up when it was enabled.

Since Swift is dropping Python2 support, and since this xcrun line causes
spurious errors during a build-script build on systems without Python2,
I am proposing we drop this xcrun -find line from build-script-impl.
Concurrency tracing was enabled depending on the presence of a header
file, but if a similarly named header was found somewhere in the path
that didn't do the same thing, that might cause problems.
Instead, we should have a build time configuration option.

This will let us save some build time without losing the coverage of
sil-verify-all everywhere since much of the code in all of the stdlibs are the
same.
