320e4747cc Codegen was silently truncating IntegerLiteralExpr's to 64 bits, bad codegen!

926a3fe671 completely reimplement floating point literals to follow the model of integer literals. 
Among other things, this gives us the amazing power to accept "var x : float = 0.0"

8ce4737534 implement "a.b" AST and type checker support. Semantics are that 'a' is evaluated and discard. 'b' is evaluated and returned.

de3c3ff04d Build an implicit expression to record the conversion 
of a oneof to its underlying type.  Much better.

55f635a0c0 Introduce an additional "context" parameter to the expression and 
statement walk callback functions, where we can stash additional
information without breaking all of the callers. 

At present, the only information in the context is the parent
statement or expression.

2e49b79617 Rename WalkOrder.h to Walk.h, and introduce typedefs for the function 
types of the expression and statement walker into it, so we don't end
up typing the same darned things over and over again.

subclasses.

0223f3edf1 Implement Expr::getSourceRange() and introduce proper support for this 
function into all of the expression nodes. Re-implement
Expr::getStartLoc() in terms of this function, and add it's brother
Expr::getEndLoc(), removing the specialized implementations.

Clean up the source ranges of implicitly-created tuple expressions in
the process.

a7c7d64fa0 Switch swift to use SourceLoc instead of SMLoc. 
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.

2711ad03c9 now that WalkOrder is in a common header, move the WalkStmt to be a 
Stmt method, rename it to just 'walk' to follow the naming convention,
and give it an accurate doc comment for good measure.

cb59d9c926 split the walkorder enum out to its own header file. This is a silly waste of 
a file, but is needed to share it between two other heads.  Header files seem
so baroque.

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
}

350b89e6e4 Represent assignments as their own AssignStmt, preserving the model we had 
before, but removing the hack where we'd represent them as a binary operator
with a null operator function.  We still have no clear semantics for what 
is valid or not.

ebc33d306f add AST support for semicolon statements and clean up the parser. While noone cares, it is trivial 
to support and good for completeness.

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.
