These changes add support for build and target configurations in the compiler.
Build and target configurations, combined with the use of #if/#else/#endif allow
for conditional compilation within declaration and statement contexts.
Build configurations can be passed into the compiler via the new '-D' flag, or
set within the LangOptions class. Target configurations are implicit, and
currently only "os" and "arch" are supported.

outside of debugger-support mode. Rip out the existing special-case
code when parsing expr-identifier.
This means that the Lexer needs a LangOptions. Doug and I
talked about just adding that as a field of SourceMgr, but
decided that it was worth it to preserve the possibility of
parsing different dialects in different source files.
By design, the lexer doesn't tokenize fundamentally differently
in different language modes; it might decide something is invalid,
or it might (eventually) use a different token kind for the
same consumed text, but we don't want it deciding to consume more or
less of the stream per token.
Note that SIL mode does make that kind of difference, and that
arguably means that various APIs for tokenizing need to take a
"is SIL mode" flag, but we're getting away with it because we
just don't really care about fidelity of SIL source files.

Also, disallow creating Modules and FileUnits on the stack. They must always
live as long as the ASTContext.

- purge @inout from comments in the compiler except for places talking about
the SIL argument convention.
- change diagnostics to not refer to @inout
- Change the astprinter to print InoutType without the @, so it doesn't show
up in diagnostics or in closure argument types in code completion.
- Implement type parsing support for the new inout syntax (before we just
handled patterns).
- Switch the last couple of uses in the stdlib (in types) to inout.
- Various testcase updates (more to come).

AttributeId: Any occurence of '@<attribute-name>' anywhere.
AttributeBuiltin: A "resolved/active" attribute. Mis-applied attributes will be AttributeId.
This provides more options for coloring attributes in a way that one can easily spot
attributes that are not applied correctly.
Swift SVN r12194
- Introduce a new TypeBase::getInOutObjectType() that strips off @inout types
- Switch stuff that is calling getRValueType() to call getInOutObjectType()
when they are stripping @inout, not @lvalue (this is primarily around
stuff working with self)
- Update testcases, some diagnostics improve around & handling.
This fixes rdar://15708430 and rdar://15729093.

(various) FunctionType::get's, ArrayType::get,
ArraySliceType::get, OptionalType::get, and a few
other places.
There is more to be done here, but this is all I plan to do
for now.

This completes the FileUnit refactoring. A module consists of multiple
FileUnits, which provide decls from various file-like sources. I say
"file-like" because the Builtin module is implemented with a single
BuiltinUnit, and imported Clang modules are just a single FileUnit source
within a module.
Most modules, therefore, contain a single file unit; only the main module
will contain multiple source files (and eventually partial AST files).
The term "translation unit" has been scrubbed from the project. To refer
to the context of declarations outside of any other declarations, use
"top-level" or "module scope". To refer to a .swift file or its DeclContext,
use "source file". To refer to a single unit of compilation, use "module",
since the model is that an entire module will be compiled with a single
driver call. (It will still be possible to compile a single source file
through the direct-to-frontend interface, but only in the context of the
whole module.)

nominal, substitute known generic parameters if possible
This should improve code completion experience for generic containers a lot:
(swift) var a = Array<Float>()
// a : Array<Float> = []
(swift) a.
...
Decl[InstanceMethod]/CurrNominal: append({#val: Float#})[#Void#]
...
Decl[InstanceMethod]/CurrNominal: each({#f: (Float) -> Void#})[#Void#]
...
Decl[InstanceMethod]/CurrNominal: enumerate()[#Array<Float>#]
...
Decl[InstanceMethod]/CurrNominal: next()[#Float?#]
...
Decl[InstanceMethod]/CurrNominal: sort({#pred: (Float, Float) -> Bool#})[#Void#]
...
Only implemented for functions. Constructors and subscripts coming soon.
