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.

inside a swift ast section in an object file so it can be passed to the
linker. The driver automatically wraps merged swiftmodules iff the target
is ELF.

Also into a separate file.
Before (swift/Serialization/SerializedModuleLoader.h):
ModuleStatus
SerializedModuleLoader::ValidationInfo
SerializedModuleLoader::ExtendedValidationInfo
SerializedModuleLoader::isSerializedAST
SerializedModuleLoader::validateSerializedAST
After (swift/Serialization/Validation.h):
serialization::Status
serialization::ValidationInfo
serialization::ExtendedValidationInfo
serialization::isSerializedAST
serialization::validateSerializedAST
No functionality change, just a lot of renaming and a bit of reorganizing.

...so that the debugger has the best possible chance of being able to load
the app properly.
We don't do this for frameworks today because we don't want to leak this
information into the public module; once we have a distinction between
"the module that ships with the framework" and "the module that goes into
the debug info" we can do this for frameworks as well.

Doing so is safe even though we have mock SDK. The include paths for
modules with the same name in the real and mock SDKs are different, and
the module files will be distinct (because they will have a different
hash).
This reduces test runtime on OS X by 30% and brings it under a minute on
a 16-core machine.
This also uncovered some problems with some tests -- even when run for
iOS configurations, some tests would still run with macosx triple. I
fixed the tests where I noticed this issue.

Rather than embed AST info directly in binaries, we now include a special
symbol table entry that points to the serialized AST as a separate file.
This requires a very recent version of ld.
We still want to support the __SWIFT,__ast section in a binary because
that's how it's modeled in dSYM, so manually test both modes in
ASTSection_linker.swift.

Now that the standard library depends on Clang headers, every single tool
needs to specifically avoid using the default module cache when
SWIFT_MODULE_CACHE_PATH is set.

Add tools/lldb-moduleimport-test, which simulates LLDB importing modules
from the __apple_ast section in Mach-O files and use it to regression-test
the new API.
