[PATCH] D52076: [CodeComplete] Add completions for filenames in #include directives.

The dir component ("somedir" in #include <somedir/fo...>) is considered fixed.
We append "foo" to each directory on the include path, and then list its files.

Completions are of the forms:
 <somedir/foo.h>
 ^-text--^^-TT-^  (TypedText)
and
 <somedir/foodir/
 ^-text--^^-TT--^

The filter is set to the filename part ("fo"), so fuzzy matching can be
applied to the filename only.

No fancy scoring/priorities are set, and no information is added to
CodeCompleteResult to make smart scoring possible. Could be in future.

Note directory iteration is currently stat-happy on unix but https://reviews.llvm.org/D51921 will fix.
