The backing property for 'foo' is now '_foo', and the projected value '$foo'.
This updates Indexing to report occurrences of foo within both $foo and
_foo occurrences (rather than just $foo - the old _foo).
FindRelatedIdents was similarlar updated, so it reports 'foo' ranges in both
_foo and $foo.
CursorInfo now reports the USR, documentation, and location of foo when invoked
occurrences of $foo or _foo, but now leaves the name, type, and annotated
declaration of _foo/$foo as is. Having the same USR ensures rename invoked on
any of them will still rename via foo. Reporting foo's documentation comment
instead is just to present something more useful to the user.
This is the final piece to get rename and findRelatedIdents to include all foo
and $foo occurrences, for example, in the set of occurrences to be renamed or
shown, regardless of whether they were initiated on a foo or $foo.
Resolves rdar://problem/51695783.
We weren't picking up all occurrences of 'x' in the cases like the below:
case .first(let x), .second(let x):
print("foo \(x)")
fallthrough
case .third(let x):
print("bar \(x)")
We would previously only return occurrences within the case statement the query
was made in (ignoring fallthroughs) and for cases with multiple patterns (as in
the first case above) we would only return the occurrence in the first pattern.
Unless you're familiar with the way the swift source code is organized,
it's not clear what "SourceDocInfo" means, or how it is different from
DocSupport, etc. Move the tests into directories that are named based
on their request (note: we already had one test under CursorInfo, which
just made things even more confusing).
