c3bbefcbaa add support for lambda expressions (anonymous functions), which are the thing that
func is sugar for.  Unfortunately, we can't use 'func' without introducing ambiguity
since decls and exprs can exist in the same context, I'm not wed to 'lambda' as the
keyword, thoughts welcome.

0fc77abf5c Per discussion on swift-dev, unify 'meth' and 'func' syntax into just 'func' syntax
where you can optionally declare a receiver type.  This is cleaner both conceptually
and in implementation, and eliminates drug references. :)

e647b29339 stop the llvm-namespace-qualification-insanity by caving in and
adding a new swift/AST/LLVM.h file which forward declares and imports
common llvm classes, starting with SMLoc.

b9e7823656 Implement lexing and parsing support for a proper if expression. There
is no AST building or typechecking support yet.  Document the intended
semantics in LangRef.  This is clearly subject to change, but is a starting
point.

7530ec988c Add a error to reject foo() when foo is not a function type. Previously we allowed it because these are two valid top-level values, but we now reject them because they are almost certainly a bug. This can be disabled by putting a space between them if this is useful for some reason.

b9fbd77f58 Fix a bunch of minor bugs found through inspection:
1. Punctuation identifiers were missing some characters.
2. Some parser production and methods were misnamed.
3. Top level var decls don't need a ; after them.
4. Various parser comments were out of date.
5. We now allow any type in a struct decl, e.g. "struct foo int", even though it's weird.

d2abfde434 introduce a new builtin type to represent the result of the else binary operator (which is a temporary hack until we get user defined types).
Use it to define ife/else.  Fix some precedence/parsing bugs that implementing else exposed.
