This commit covers the basic functionality of protocol inheritance, including:
- Parsing & AST representation
- Conforming to a protocol also requires conforming to its inherited
protocols
- Member lookup into a protocol also looks into its inherited
protocols (results are aggregated; there is no name hiding)
- Teach ErasureExpr to maintain lvalueness, so we don't end up
performing a silly load/erase/materialize dance when accessing
members from an inherited protocol.

multiple times, as well as teaching the name lookup mechanism that
it's similarly rude to report ambiguous results because it searched
the same import twice. Fixes <rdar://problem/11287213>.
Yes, this is a bit of an ugly hack.

and is just an unmanaged pointer. Also, introduce a basic swift.string type.
This is progress towards rdar://10923403 and strings. Review welcome.

anonymous member is actually one of these.
A func decl is curried over all of its parameter clauses,
as long as they're written without parentheses. So the body
of a func is the body of the "most curried" function:
func foo(x:int) -> (y:int) -> int {
// This is the body of the function that takes 'y'.
// It returns an int.
}
func bar(x:int) -> ((y:int) -> int) {
// This is the body of the function that takes 'x'.
// It returns a functon of type (y:int) -> int.
}

that LLVM supports. The standard library still only exports float and double,
but the swift core should be more general. Yay for PPC128 :)

Also use the new getAdvancedLoc() method instead of hacking
on SMLoc directly.
Also fix the warning/note/error methods to forward through ASTContext
instead of being replicated everywhere.

diagnostics over to it.
There are a few differences between this diagnostic engine and Clang's
engine:
- Diagnostics are specified by a .def file (Diagnostics.def), rather
than via tblgen, which drastically simplifies the build and makes
code completion work when you add a new diagnostic.
- Calls to the "diagnose()" method are safely typed based on the
argument types specified in the .def file, so it's harder to write a
diagnostic whose expected arguments (in the string) and whose actual
arguments (in the code) don't match.
- It uses variadic templates, so it hangs with the cool kids.

have two different ways to represent the same thing. This has the pleasant bonus that stuff
crashes when you do things with unresolved types.

types off of ASTContext onto the types themselves. This
never made sense for clang, and makes the same amount of sense
for swift. Start with function types.
