For now, just emit a warning. Later on we can actually get this right for
multiple files.
This is important for people manually trying to reduce run lines that come
from Xcode.

Without this, clients that don't use a CompilerInstance (like LLDB) won't
have target configuration options available.
Also, move minimum OS checking into the driver. This makes sure the check
happens early (and only once), and in general fits the philosophy of
allowing the frontend to use configurations that might be banned for users.

This doesn't really affect anyone in real life, but it will catch cases
where someone's trying to compile for iOS without the iOS stdlib around.

This option implicitly imports the Clang module with the same name as the
module being built into every source file in the module being built.
This will be used for mixed-source framework targets to give Swift code the
same implicit visibility for Objective-C decls in the same module that it
already has for other Swift decls.

The driver infers the filename from the module file by replacing the extension,
and passes the explicit path to the swiftdoc file to the frontend. But there
is no option in the driver to control emission of swiftdoc (it is always
emitted, and name is always inferred from the swiftmodule name).
The swiftdoc file consists of a single table that maps USRs to {brief comment,
raw comment}. In order to look up a comment for decl we generate the USR
first. We hope that the performance hit will not be that bad, because most
declarations come from Clang. The advantage of this design is that the
swiftdoc file is not locked to the swiftmodule file, and can be updated,
replaced, and even localized.

This is important so that other parts of the compiler (e.g., AST verifier) are
less strict about AST invariants.
Alternatively, we could make sure to emit a diagnostic in the parser when we
consume the code completion token, but chasing every place where we do it now
(and remembering to do this in future) does not scale well.

Added DiagnosticsDriver.def and DiagnosticsDriver.h for driver-only diagnostics.
(Diagnostics which are shared with the frontend remain in
DiagnosticsFrontend.{def,h}.)
Added a DiagnosticEngine& to Compilation, so that it can emit diagnostics for
events which occur while performing Jobs.
Replaced all of the locations where we were manually printing error messages to
emitting real diagnostics, adding diagnostics if necessary.
Updated Driver::buildCompilation() so that it fails early if any errors were
encountered.
Updated test/Driver/actions.swift to pass a -module-name for multi-input tests.

Thanks to the way we've set up our diagnostics engine, there's not actually
a reason for /everything/ to get rebuilt when /one/ diagnostic changes.
I've split them up into five categories for now: Parse, Sema, SIL, IRGen,
and Frontend, plus a set of "Common" diagnostics that are used in multiple
areas of the compiler. We can massage this later.
No functionality change, but should speed up compile times!
