We assume that libclang does not return any duplicates, at least we
never noticed any so far. For the concrete test below no duplicates were
removed.
Function overloads are not problematic because they are folded into one
ClangAssistProposalItem (addOverload()).
To the completion items from libclang we add the Qt Creator snippets as
items. Those might have the same text in the completion list view, but
their icon is different (e.g. consider the keyword completion "class"
and the Qt Creator snippet "class"), thus the user can still tell them
apart.
Test:
1. Open src/plugins/clangstaticanalyzer/unit-tests/qt-essential-includes.pro
2. Open main.cpp
3. Complete in the main function
Measured with a timer in IpcReceiver::codeCompleted.

Now: 66ms (avg)
Gain: 11%

1 struct Foo { int member; };
2 void f(Foo *foo)
3 {
4 foo.<REQUEST COMPLETION> // correct '.' to '->' and provide results
5 }
The preferred approach would be to check if "foo" in line 4 is of
pointer type, but there is no suitable cursor (only CompoundStmt) at
that position since the code is usually not yet parsed and thus invalid.
Thus, just run the completion as is. If there are not any results for a
dot completion, re-run the completion with "." exchanged by "->". This
approach is inherently slower than the preferred approach implemented in
the built-in code model.
The following rare cases are not handled:
1) Requesting completion after white space:
Works: foo.<COMPLETE HERE>
Fails: foo. <COMPLETE HERE>
2) Opening a file and requesting completion (ctrl+space) without prior
editing. No editing before triggering completion means that no
unsaved file is generated on the backend side, which is a
requirement for the correction.
