I also added a macro called INITIALIZE_LLVM(argc, argv) which moves this logic
into one place and should be used at the beginning of *all* binaries. It
initializes an LLVM shutdown object, sets up the pretty stack trace, and then
initializes all of the parts of LLVM. This will make it easy to update this in
the future.
The reason why a macro was required was because of llvm_shutdown_obj, an RAII
object that cleans up LLVM. It has to be at the function level scope of the main
function.

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

Swift SVN r30247
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.

To get this to work, delay some "cleanup" work in the
demangler. For example, we now preserve in the tree
whether something was mangled as an allocating
initializer, and we only special-case the class vs.
non-class cases in the pretty printer.
Also fixes a number of remangling bugs, of course.
Swift SVN r24534
demangling tree back into a mangled string.
Also, extend the demangling API in a few obvious
ways, and simplify testing for failure in the
node-returning APIs by having them simply return
null instead of a spurious Failure node.
Also, preserve slightly more information in the
demangling tree. The goal here is eventually to
always allow a perfect round-trip through the
demangler parse tree. This patch gets us close,
but we're not quite there yet.
Tests to follow.
Swift SVN r24473
The new demangler is in the "swift/SIL/Demangle.{h|cpp}" files, and in the swift::Demangle namespace, which has two public entry points:
std::string demangleSymbol(llvm::StringRef mangled);
std::string demangleType(llvm::StringRef mangled);
This was necessary to support the need for LLDB to demangle Swift symbol (and type) names
Test case is included
