Local functions may reference each other as long as they don't transitively capture any vars or other non-function local decls before their declaration.

This location is used when deciding whether a capture has already been
initialized, and without it the compiler decides that the reference to
a name from the capture list should be rejected.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

This addresses the bulk of <rdar://problem/15344950>, which involes us
not being able to find local variable declarations in expressions when
the parser didn't pre-bind them for us.
The fix to name lookup itself insures that a case such as
case (var a, a)
doesn't allow the second 'a' to find the first.

There is a special-case hack to allow capture of 'this', which is
implicitly [byref] for structs. At the moment, most of the cases where
this hack is necessary are [auto_closure] parameters (for assertions
and &&/||).
