59db25658a Ban the use of SuperConversionExpr to produce lvalues, since that is, 
in general, not sound. For the limited cases where we did use this
expression kind on lvalues (member access or instance method
invocations on a superprotocol), leave the conversion to the client of
their respective AST nodes (MemberRefExpr, DotSyntaxCallExpr). We may
decide to enrich these ASTs in the future with more information about
the conversion path, but it's not clear that it's actually useful
information for, e.g., IRgen.

8617d1733d Change the IR translation of struct types to just require a single 
level of IR struct type.  At first we were emitting two layers
because structs were secretly tuples, and then more recently
we were emitting two layers to avoid having to adjust a bunch
of tests.  Just bite the bullet now;  it makes the IR a lot
cleaner, and it's never going to be easier.

a49d6c88c8 Introduce a conversion-to-supertype expression to capture conversions 
from a protocol to a protocol it inherits. This is a far simpler
operation that the general type-erasure expression, so generate this
AST when we can.

875d914c77 Extract the layout logic out of GenTuple.cpp into a template header. 
It does seem silly for this to all be templated, but I couldn't
really see a very elegant solution given how I wanted things to
be genericized.

...interestingly, a ?t.t[] type would have done nicely for some
of this.

70bfc235b8 Implement protocol inheritance, e.g., 
protocol Document { var title : String }
  protocol Versioning { func bumpVersion() }
  protocol VersionedDocument : Document, Versioning { }

This commit covers the basic functionality of protocol inheritance, including:
  - Parsing & AST representation
  - Conforming to a protocol also requires conforming to its inherited
  protocols
  - Member lookup into a protocol also looks into its inherited
  protocols (results are aggregated; there is no name hiding)
  - Teach ErasureExpr to maintain lvalueness, so we don't end up
  performing a silly load/erase/materialize dance when accessing
  members from an inherited protocol.

204b416229 raw_fd_ostream doesn't set the "has_error" bit in its ctor if it failed to open the file, it returns the error through the string reference error argument. This is half of fixing rdar://11388418.

f75e305a20 Add ScalarToTupleExpr to represent an implicit conversion from a scalar to a tuple, with or without default arguments. Make Sema and IRGen work with them. 
I'm not completely sure this is the representation we want, but it isn't much code to rip out if we decide to represent it some other way.

While I'm in the area, also fix a case where tuple->tuple conversion wasn't working.

2f44c0038c Initial stab at implementing string literal interpolation for simple expressions, 
e.g. "foo is \(i+j)".  This implements rdar://11223686

Doug implemented all the hard parts of this.  I ripped out support for nested string
literals (i.e. string literals within an interpolated string), which simplified the
approach and defined away some problems with his patch in progress.  I plan a few refinements
on top of this basic patch.
