I introduce the new infrastructure supporting recursive timers in Clang. This patch is based on https://reviews.llvm.org/D45619 [Time-report] (1) and it is not the last one in this series. The main idea is a possibilty to have "horizontal" timers instead of "vertical" ones which we have today. The patch alows to find the most critical functions (from compilation time of view) and to to analyze them.
