Return type in the closure signature is often redundant when expanding
placeholders, because the type of the clossures are usually inferred
from the context (i.e. calling function), users don't need to write the
return type explicitly.
They are not only redundant, but also sometimes harmful when the return
type is a generic parameter or its requirement. Actually, there is no
correct spelling in such cases.
So omit the return type and the parentheses around the parameter clause.

This affects module interfaces, interface generation in sourcekitd, and
diagnostics. Also fixes a fixit that was assuming the 'OSX' spelling when
computing the source range to replace.

Most of the changes fall into a few categories:
* Replace explicit "x86_64" with %target-cpu in lit tests
* Cope with architecture differences in IR/asm/etc. macOS-specific tests
Do not remove semantic annotations, so that if a client sends multiple
magic replacetext 0, 0, "" requests they will all return the same
result. This makes sourcekitd more robust around providing semantic
highlighting if the editor may make multiple queries for document
update.

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.
```
