Clang: Add clang query Clang query is mechanism to use AST matcher to search for code. Think about regular expression but in the context of AST. So you get a semantic search tool for C++. Change-Id: I72e882c5b53a0c52f352a3664847c4c3e4f6fc2e Reviewed-by: Tim Jenssen <tim.jenssen@qt.io>

UnitTests: Fix names and disable slow tests by default Slow and very slow tests have now their own test category. We add SlowTest for tests which are slower than ~5ms and VerySlowTest if they are slower than ~100ms. They are disabled them by "-*SlowTest.*". If you have a faster machine than most developers simply try lower values. The aim is that most developers can execute the tests in under ~2s. In the long run we should use dependency breaking and data sharing to reduce the count of the slow tests.
