Clang: Show function signature hint for constructors and functors

Browse Source 
For "foo(|" [1] we requested a completion from libclang with the cursor
position just before "foo" and then filtered the function declarations
for functions matching the name "foo". This worked fine for ordinary
functions, but obviously not for constructors and functors.

Recent versions of libclang support proper function call completion with
XCursor_OverloadCandidate, so make use of that.

[1] '|' represents the cursor position
