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

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.

9995a39aae Switch Expr::getLoc() over to an implementation that defaults to the
starting location of the expression, but can be overridden by
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.

da564d50d3 A long journey later, implement support for type inference of integer literals instead of
forcing them to int64 all the time.  Now the integer_literal_type in the standard library
is only used to resolve ambiguity in expressions.  Among other amazing things, we now
correctly accept:

  var x8 : int8 = 4

without a cast.

This still isn't doing any bounds checking and isn't checking the inferred type to tell if
it is compatible with integer literals (i.e. has a primitive conversion function from the
LLVM IR type).  Enough for now though.

This is progress towards rdar://10357238.

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,

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.

a8e2788184 implement semantic analysis for FuncExpr and have the parser lower func decls
to func exprs.  All the tests pass again.  Now we have a strict equality 
between:

  func foo(a : int) -> int { a+1 }

and 

  var foo = func(a : int) -> int { a+1 }

except we don't support the later syntax yet.  We also really need return, though
we're getting closer to being able to usefully support it.

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.
