Summary: This adds three Function methods to handle function entry counts: setEntryCount() and getEntryCount(). Entry counts are stored under the MD_prof metadata node with the name "function_entry_count". They are unsigned 64 bit values set by profilers (instrumentation and sample profiler changes coming up). Added documentation for new profile metadata and tests. Reviewers: dexonsmith, bogner Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D9628 llvm-svn: 237260
