Out of all operating systems ever supported by Swift, only Ubuntu 14.04
had libstdc++ 4.8, and Swift has sunset support for Ubuntu 14.04 for a
while now.
Using \0 as a representation of the cursor position is a implementation
detail and is done by SourceKit. Client including complete-test should
not do it.
This inserted test used to be treated as EOF in compiler so the code
after the completion position is completely ignored.
* 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.
Ideally we would have precise completion for all our keywords; for now,
just imporove handling of 'return', which we can do by checking if the
current context is a function/closure/init/subscript/etc.

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.
