This commit leaves 'var' on function parameters as a warning to be
merged into Swift 2.2. For Swift 3, this will be an error, to be
converted in a follow-up.

3434f9642b Disallow 'var' pattern bindings in if, while, and guard statements
Make the following patterns illegal:

  if var x = ... {
    ...
  }

  guard var x = ... else {
    ...
  }

  while var x = ... {
    ...
  }

And provide a replacement fixit 'var' -> 'let'.

64100010dd Allow capturing from another TopLevelCodeDecl.
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.
