And include some supplementary mangling changes:
- Give the first generic param (depth=0, index=0) a single character mangling. Even after removing the self type from method declaration types, 'Self' still shows up very frequently in protocol requirement signatures.
- Fix the mangling of generic parameter counts to elide the count when there's only one parameter at the starting depth of the mangling.
Together these carve another 154KB out of a debug standard library. There's some awkwardness in demangled strings that I'll clean up in subsequent commits; since decl types now only mangle the number of generic params at their own depth, it's context-dependent what depths those represent, which we get wrong now. Currying markers are also wrong, but since free function currying is going away, we can mangle the partial application thunks in different ways.

'Ss' appears in manglings tens of thousands of times in the standard library and is also incredibly frequent in other modules. This alone is enough to shrink the standard library by 59KB.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

Refuse to load a module if it was compiled for a different architecture or
OS, or if its minimum deployment target is newer than the current target.
Additionally, provide the target triple as part of pre-loading validation
for clients who care (like LLDB).

Changing the design of this to maintain more local context
information and changing the lookup API.

Locally scoped type declarations were previously not serialized into the
module, which meant that the debugger couldn't reason about the
structure of instances of those types.
Introduce a new mangling for local types:
[file basename MD5][counter][identifier]
This allows the demangle node's data to be used directly for lookup
without having to backtrack in the debugger.
Local decls are now serialized into a LOCAL_TYPE_DECLS table in the
module, which acts as the backing hash table for looking up
[file basename MD5][counter][identifier] -> DeclID mappings.
New tests:
* swift-ide-test mode for testing the demangle/lookup/mangle lifecycle
of a module that contains local decls
* mangling
* module merging with local decls
Swift SVN r24426
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.

-enable-source-import doesn't play nice with debug info, and we want to be
able to run all tests with -g added. The last few tests that require
-enable-source-import could be built with --no-debug-info, or however we
end up spelling that.

You can still mark them @objc explicitly (or @IBOutlet, or anything else that
would require ObjC interop).
Also, don't print private decls in the generated header, whether @objc or not.
not.
Swift SVN r19733
We do this hack for @objc methods at the top level, emitting them as external in SIL and making them private in IRGen, to prevent SIL optimizations from dropping the functions as unused (see <rdar://problem/17074598>), but we weren't doing so for @objc classes in local contexts, and they were getting dropped. Fixes <rdar://problem/16982281>.
Swift SVN r18668
This is still a kludge setting the visibility of ObjC thunks at IRGen rather than SILGen time, but resolves <rdar://problem/16906857>.
