Although I don't plan to bring over new assertions wholesale
into the current qualification branch, it's entirely possible
that various minor changes in main will use the new assertions;
having this basic support in the release branch will simplify that.
(This is why I'm adding the includes as a separate pass from
rewriting the individual assertions)
Previously it was part of swiftBasic.
The demangler library does not depend on llvm (except some header-only utilities like StringRef). Putting it into its own library makes sure that no llvm stuff will be linked into clients which use the demangler library.
This change also contains other refactoring, like moving demangler code into different files. This makes it easier to remove the old demangler from the runtime library when we switch to the new symbol mangling.
Also in this commit: remove some unused API functions from the demangler Context.

This avoids linking parts of the llvm utilities into the library.
It fixes an option-registere-more-than-once problem in the SwiftDemangle unit test.

Break up "Simplified" demangling mode (shortened demangled descriptions
for the sake of displaying in UI with small areas) into more
fine-grained options instead of an opaque "Simplified" option and
provide a static preset of options for displaying stack traces in
Xcode UI and other tools, for example.
- Don't print unmangled suffixes
- Don't print module names
- Shorten various generic specialization descriptions as just
"specialized"
- Don't display long protocol conformances
- Truncate where clauses
- Don't display so-called "entity" types
- Shorten "partial apply *"
- Shorten thunk phrases
- Shorten value witness phrases
- Truncate archetype references

To support UI applications displaying demangled names in a limited
amount of screen space, provide a new SwiftDemangle API and Demangler
option to do the following:
- Skip all module name prefixes when printing contexts
- Don't print implicit self/metatype parameters when printing
function types
Add a '-simplified' flag to swift-demangle to support testing at the
command line.

This library becomes a permanent interface that we would need to support
in the long term, so we should get dylib names and APIs right.
