76e15b8472 make the SIL parser put basic blocks in the order that they are defined, not 
the order they are referenced.  Fix a testcase to use control flow instead
of producing invalid SSA to test forward refs of values, fixing a FIXME.

be0f7b4c48 Wire up initial support for function_ref, allowing us to SILParse the code for "return 4". 
This is terrible in several ways: it doesn't handle forward references, we do a linear scan
of SILFunctions, and diagnostics don't exist.  Room for improvement some other time.

9cf535be31 after parsing an applyinst, actually create it! We can now silparse 
the sil for this function:

e052f3ca41 change the sil printer to print the type of the destination 
operand, producing something like:

	%2 = store %0 to %1 : $*Int64

Enhance the sil parser to be able to parse this.  We can now
round trip everything required to handle this function:

func foo(a : Int) -> Int {
  return a
}

2e69c61f71 Implement more reasonable local value name lookup: 
- Allow forward references.
  - Diagnose redefinitions.
  - Diagnose cases where the use/def of a value mismatch type.

While I'm at it, this fixes a bug where tuple parsing wasn't parsing
the separating commas.

return instructions.

minimal testcase parsing (but ignored).

e0527c8a84 simplify resolveIdentifierType() in two ways: 
1) a DeclContext doesn't need to be passed in, now that IdentifierType tracks it.
2) factor the code that sets Components to ErrorType out of the clients.

8c85a49d2a with the groundwork out of the way, we can now namebind types referenced 
by the SIL parser.  Add a test that covers both local types, and types
that require looking through an import decl (Int, from the stdlib).

1fde9f69fd remove the diag::tuple_global_missing_type diagnostic, which printed as 
"a tuple type specifying the type of a global must explicitly state the type of each tuple element".

This diagnostic doesn't make any sense, and is apparently only generated by the old
type checker.  It is also the only thing keeping the "isFirstPass" argument to
TC.validateType() alive, so remove it.

The new type checker does have issues with default values, I filed 
rdar://13946171 to track it, but this old approach (which I wrote, *shame*) 
seems way too broken to salvage.

b4e7ab4247 use TypeLowering to produce SILTypes that make sense now that aggregates 
have been simplified.  This still isn't ideal, but is a lot better than
what we had, and is waiting for SILFunctionTypeInfo to stop containing
SILTypes.
