Introduce a '.metatype' form in the syntax and do some basic
type-checking that I probably haven't done right. Change
IR-generation for that and GetMetatypeExpr to use code that
actually honors the dynamic type of an expression.

- I've converted every document except the LangRef, which is more trouble to
convert because of the use of styling to embed notes.
- 'make html' with sphinx-build in your path to build the docs.
Now back to my regularly scheduled breaking things. :)

resulting token goes back through the lexer to get the appropriate
token kind. Thanks to Chris for spotting this.
Also, document the '<' and '>' splitting behavior in LangRef.

and use this information as cues in the language. Right now,
we do not accept things like "-- *i" because the prefix
operator is not correctly right-bound; instead you have to
write "--(*i)". I'm okay with that; I did add a specialized
diagnostic recognizing operator-binary in a place where we're
expecting a potential operator-prefix.

protocols the underlying type of the type alias shall conform to. This
isn't super-motivating by itself (one could extend the underying type
instead), but serves as documentation, makes typealiases provide the
same syntax as other nominal types in this regard, and will also be
used to specify requirements on associated types.

classes, with the same syntax as we have on protocols. This
inheritance specifies explicit conformance to a protocol.
Later, we can allow a class definition to have a single class type
within this list, when we introduce class inheritance.

protocol Document { var title : String }
protocol Versioning { func bumpVersion() }
protocol VersionedDocument : Document, Versioning { }
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.

implementing rdar://11360347 / 11349750. C-style for loops could be
further enhanced by allowing a comma-separated list of statements in
the increment, but this isn't something I plan to do in the short term.

the appropriate slice type and check the bounds. The
first bound must be a literal or a type with a
getArrayBoundValue method, which has the same recursive
nature as getLogicValue (i.e. it can return a type that
has a getArrayBoundValue that returns an integral type,
but that's it; it's capped at one hop). The rest
of the bounds must be empty (meaning a slice) or
constant under the same conditions as fixed-size
array types.

to the type named by A (when A is in fact a direct reference to a
type). If that coercion would fail, then fall back to invoking a
constructor. Fixes <rdar://problem/11272190>.

Per discussion, this should probably be "no newline since the last
token", but that decision should be made simultaneously for ( and [.
