Looking at the SIL I came to the conclusion that `Unmanaged` ins fundamentally broken.
It's easier to directly bitcast between bridged and native SIL objects. It also produces simpler SIL which can be further optimized
Let's lldb's `po` command not print any "internal" properties of the conforming type.
This is useful if the `description` already contains all the information of a type instance.
For two reasons:
* We also like to check for assert failures in release builds. Although this could be achieved with `precondition`, it's easy to forget about it and use `assert` instead.
* We need to see the error message in crashlogs of release builds. This is even not the case for `precondition`.
Also, re-export the "Basic" module in "SIL" so that the new assert implementation is also available in the Optimizer module (where all files import SIL).
C++ interop is now enabled in SwiftCompilerSources, so we can remove some of the C bridging layer and use C++ classes directly from Swift.

To use _RegexParser from SwiftSyntax.
* Create 'libswiftCompilerModules_SwiftSyntax.a' which is a subset of
'libswiftCompilerModules.a'
* Link 'lib_InternalSwiftSyntaxParser' to
'libswiftCompilerModules_SwiftSyntax.a'
* Factor out swift runtime linking logic in CMake so that dynamic
libraries can link to Swift runtime, in addition to executables
* Link 'lib_InternalSwiftSyntaxParser' to swift runtime
and introduce the StringRef struct.
It's more efficient.
Also, rename the `HasName` protocol to `HasShortDescription`, which introduces the new requirement `shortDescription`. This is need because `name` now has `StringRef` type and not `String` anymore
This fixes:
* An issue where the diagnostic messages were leaked
* Diagnose at correct position inside the regex literal
To do this:
* Introduce 'Parse' SwiftCompiler module that is a bridging layer
between '_CompilerRegexParser' and C++ libParse
* Move libswiftParseRegexLiteral and libswiftLexRegexLiteral to 'Parse'
Also this change makes 'SwiftCompilerSources/Package.swift' be configured
by CMake so it can actually be built with 'swift-build'.
