63a09007a1 [Threading] Create new threading library and use it. 
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.

dadcb04ae2 [Build][Runtime] Replace SWIFT_STDLIB_SINGLE_THREADED_RUNTIME. 
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.

Turn off the GenericSignatureBuilder

703d89c8bd Turn off the GenericSignatureBuilder 
The Requirement Machine has been enabled in 'verify' mode for a while,
where we run both the GenericSignatureBuilder and Requirement Machine
minimization algorithm and compare the results, with the
GenericSignatureBuilder being used to emit diagnostics.

Now, it's time to flip the flags to 'enabled' mode, where the
GenericSignatureBuilder doesn't run at all, and the Requirement Machine
emits diagnostics. This finally allows us to realize the correctness
and performance gains from using the Requirement Machine.

See https://forums.swift.org/t/the-requirement-machine-a-new-generics-implementation-based-on-term-rewriting/55601/9
for details.

392e02d58f Rather than turning off sil-verify-all on all stdlib builds... Re-enable it only on the macOS x86_64 platform. 
Most of the stdlibs at the SIL level are the same so by not verifying them all,
we aren't losing that much coverage. This gives us back some of the coverage we
lost when we disabled -sil-verify-all everywhere without causing us to have the
huge slow down when building multiple stdlibs.

59feb67645 [build-script] Add support for running sil-verify-all only on macOS x86_64. 
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.

65bffd7ad7 Add _MatchingEngine and _StringProcessing modules. 
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`.
