Attempt to properly quote the python interpreter path in the lit
configuration. This was quoted in some places but not others. This
attempts to homogenise the path quoting.
We weren't printing memberwise inits, shorthand arguments (e.g. $0, $1), and
other implicit decls, so cursor info would give empty annotated decl and fully
annotated decl fields for them.

getSingleFrontendInvocationFromDriverArguments is set up to never produce file
lists in the output frontend arguments, but since the driver accepts file lists
as input arguments, this should too.
We would previously hide the protocol, its extensions and members, but the '_'
prefix really just means the protocol itself isn't intended for clients, rather
than its members.
This also adds support for 'fully_annotated_decl' entries in doc-info for
extensions to be consistent with every other decl, and removes the
'fully_annotated_generic_signature' entry we supplied as a fallback.
Also fixes several bugs with the synthesized extensions mechanism:
- The type sustitutions applied to the extension's requirements were computed
using the extension itself as the decl context rather than the extension's
nominal. The meant the extension's requirements themselves were assumed to
hold when determining the substitutions, so equality constraints were always
met. Because of this extension members were incorrectly merged with the base
nominal or its extensions despite having additional constraints.
- Types within the requirements weren't being transformed when printed (e.g.
'Self.Element' was printed rather than 'T') both in the interface output and
in the requirements list. We were also incorrectly printing requirements
that were already satisfied once the base type was subsituted in.
- If both the protocol extension and 'enabling' extension of the base nominal
that added the protocol conformance had conditional requirements, we were
only printing the protocol extension's requirements in the synthesized
extension.
- The USR and annotated decl output embedded in the 'key.doc.full_as_xml'
string for synthesized members were printed to match their original context, rather than
the synthesized one.

This attribute is intended to mean there's a replacement declaration that
should be used instead in Swift code. We already filter out decls with this
attribute in code completion, but were still exposing them in generated
interfaces.

While the decls being printed for header file generated interfaces were mapped
from the top-level clang decls in that file, the Swift decls they correspond to
may not be top-level. E.g. top-level functions in the header file can be mapped
to property accessors on the Swift side, which were being printed simply as
"get" at the top level.
This updates header interface generation to map each decl to its top-level decl
before printing.

Don't column align PBD entries if any entry spans from the same line as
the var/let to another line. E.g.
```
// Previous behavior:
let foo = someItem
.getValue(), // Column-alignment looks ok here, but...
bar = otherItem
.getValue()
getAThing()
.andDoStuffWithIt()
let foo = someItem
.getValue() // looks over-indented here, which is more common.
getOtherThing()
.andDoStuffWithIt()
// New behavior
getAThing()
.andDoStuffWithIt()
let foo = someItem
.getValue() // No column alignment in this case...
doOtherThing()
let foo = someItem
.getValue(), // Or in this case (unfortunate, but less common)...
bar = otherItem
.getValue()
let foo = someItem.getValue(),
bar = otherItem.getValue() // but still column-aligned in this case.
```

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.
When producing frontend arguments for sourcekitd, force the output mode
to -typecheck so that we do not create any temporary output files in the
driver. Previously, any sourcekitd operation that created a compiler
invocation would create 0-sized .o file inside $TMPDIR that would never
be cleaned up.
The new swift-driver project handles temporaries much better as
VirtualPath, and should not need this approach.

Opaque result type syntax is not usable except the declaration of
itself. In other places, users need to let them inferred. If they are
inferred associated type, they need to reffered by the name of the
associated type.
