Make the following patterns illegal:
if var x = ... {
...
}
guard var x = ... else {
...
}
while var x = ... {
...
}
And provide a replacement fixit 'var' -> 'let'.

Otherwise, we'll fail to capture "locals" declared in top-level guard
statements. This led to an assertion failure in SILGen.
Depends on previous commit.

init()'s implicitly evaluate the initial values for properties, and we aren't modeling
that correctly in the AST. This prevented the closure checker from noticing these
accesses, leading to SILGen crashing later. In the absence of proper AST modeling of
this, add special case handling for them.
Swift SVN r29508
Special-casing these as MemberRefExprs created an asymmetry
where unbound archetype instance methods (<T : P> T.f) could
not be represented. Treating class and protocol methods
uniformly also eliminates a handful of special cases around
MemberRefExpr.
SILGen's RValue and call emission peepholes now have to know
about DeclRefExprs that point to protocol methods.
Finally, generalize the diagnostic for partially applied
mutating methods to any partially applied function with an
inout parameter, since this is not supported.
Fixes <rdar://problem/20564672>.

Properly implementing a class whose methods capture variables
defined in the outer scope requires adding the captures as
hidden vars in the class and initializers, and seems
non-trivial.
Just diagnose this case for now instead of crashing.

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.
Swift SVN r28394
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.
Swift SVN r9858
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 &&/||).
