This patch uses the new function profile metadata "function_entry_count" to annotate entry counts from sample profiles. In a sampling profile, the total samples collected at the function entry are an approximation for the number of times that function was invoked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237265 91177308-0d34-0410-b5e6-96231b3b80d8
