ce7403dd1e implement IRGen of escapes. High unicode escapes aren't handled yet, but all the 
basics are.

b8b1694564 Complain about file names that aren't valid identifiers. 
When we divide the world into scripts and modules, this
won't matter for the former.  Recognize <stdin> as a
special case;  it should instead just always be a script.
Fixes rdar://problem/10986311.

1076367d73 implement rdar://10962528 - split up the int/fp literal lexing and grammar. 
This cleans up handling of int/fp literals by splitting them appart at the
lexer level.

the end of the current token, and use it for proper translation from
SourceRange to SMRange when printing diagnostics.

fc183b9cc3 Decouple the lexer from the ASTContext and specific BufferID. They 
aren't needed for the lexer proper (which just needs a buffer to dig
through). Also, make it possible to suppress lexer diagnostics merely
by not giving it a diagnostic engine to work with.

d0dd4d44bc Surface the Token and Lexer headers as public headers, since we're

26f66a8b24 move all the parser headers into lib/Parse since they are now all private. 
I chose to just delete the -lex action in swift, since it was only useful for
about 10 minutes during bringup and probably never will be again.

33f774f9b7 Rearrange a bunch of code for better layering: instead of Parser depending on Sema, 
just move the Sema code into the Parser library.  There is no way to use one without
the other.  The library formerly known as Sema will get renamed.

Chris Lattner
0e8a66ec9d Introduce a new ParseResult<T> helper class, which is effectively 
oneof { T*, Absent, ParseError, SemaError }.

This replaces the former convention used by the expression parsing
logic that used NullablePtr + bool to indicate all of these states,
in a way that I could never keep straight.

This should lead to better error recovery, but needs to be adopted by
more parts of the parser.  Sema still uses NullablePtr because it
either returns a valid AST node or has a semantic error, there is no
parse error possible in Sema.

The consumeToken(Tok.getKind()) is terrible, but will disappear when
most of these cases have operators stripped out.

433d6de807 implement AST and parser support for 'return'. We're still not doing a conversion 
to a return type yet though.  We happily diagnose thigns like this as an error:

func foo() -> int {
  return 4 5
}

a64c74ec94 Replace lambda keyword with func. One annoying aspect of this that I didn't 
think about will occur when/if we want to support attributes on func expression.
That should look like "func [attributes]{ ... }" but now that requires looking
beyond that attributes to know if this is a funcdecl or funcexpr.  Nothing that
more heroic lookahead can't handle.

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.

63ce0be641 make the big switch: {} are now statements, not expressions. This removes some 
annoying things from the grammar (like expr-non-brace), and makes it so that 
the body/else of an if is just a statement.

This patch has a fairly serious caveat that we just drop function bodies on the
floor now, since we have no "stmtexpr" sort of thing to represent the syntactic
sugar that is func.  We'll fix that soon.

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. :)
