7b29a420f6 Design and implement the [byref] attribute, checking that 
it doesn't appear in places it shouldn't.  The only limits on
this checking right now is the inadequacy of location information
for types, which is something we ought to fix.

Fix type-checking of byref applications.  Fix IR generation
of byref variables.  Whole lotta fixin' goin' on.

But hey, byref calls work.

7f60469fdf Introduce the notion of a "fully-typed" type, necessary 
because tuple types can have defaulted elements.  Check for
it and complain in function signatures.

eac219bee8 Rework the decl grammar a bit: now "decl" doesn't include import 
declarations, but they are explicitly allowed at translation unit scope.
This also introduces a parseDecl method which does the obvious thing.

80caaa7d87 remove support for anonymous oneof types, which cause issues for mangling 
and are more of a theoretically good idea than an actually useful idea.

828045f8b5 make the dot optional in tuple literals, now you can use 
foo(x = 4, 7) instead of foo(.x = 4, 7).  This resolves
rdar://10157455

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.

4a5c409408 Change the stdlib so that int is just a typealias for int64, not its own unique type. 
Update langref to describe the builtin module as an implementation detail of the stdlib,
expand the stdlib a bit.

af4d36f463 Eliminate the 'unary' attribute, instead just know that operators 
that take a single argument are unary.  Move a bunch of semantic
checking of operators from the parser to TypeCheckDecl now that it
has a decent place to hold it.
