`FreeTypeVariableBinding::GenericParameters` mode allowed to bind
all free type variables with fresh generic parameter types, which
is incorrect (at least) if there are multiple generic solutions
present, because such parameters couldn't be compared.
This mode was used for code completion, which is now switched to use
`FreeTypeVariableBinding::UnresolvedType` instead.
The index may be at the end of the ArrayRef of chunks if the completion
ends with a simple parameter with no type annotation. Check that the
index is in-bounds before adding text.

Code completion had the ability to use declarations to provide better
code completion results for postfix completions, e.g., calls to
functions/methods, but it wasn't trying to get these declarations from
anywhere. Now, get these declarations from the solution to the
constraint system.
The impetus for this is to use default-argument information from the
declaration rather than the type, but plumbing this information
through also means that we get proper "rethrows" annotations, covered
by <rdar://problem/21010193>, and more specific completions in a
number of other places.
Fixes <rdar://problem/21010193>.
* A bunch of them require objc_interop because they import code containing
Objective-C.
* Many others fail on Ubuntu 14.04 because the C++ there doesn't have a
functional std::regex implementation which is required by the
`complete-test` tool.
It may be possible to adjust some of these tests in the future to not
need these extra requirements, but this is a straightforward way to
clean up Linux test results for now.
In the new code-completion code path, force any known operators to go
through a fixed sort order. To identify operators unambiguously, add a
new BuiltinOperator code-completion kind to handle non-decl operators
(!, ., ?., and =).

All refutable patterns and function parameters marked with 'var'
is now an error.
- Using explicit 'let' keyword on function parameters causes a warning.
- Don't suggest making function parameters mutable
- Remove uses in the standard library
- Update tests

The code goes into its own sub-tree under 'tools' but tests go under 'test',
so that running 'check-swift' will also run all the SourceKit tests.
SourceKit is disabled on non-darwin platforms.
