Detailed Description
Use gcov_type to hold basic block counters. Should be at least 64bit. Although a counter cannot be negative, we use a signed type, because erroneous negative counts can be generated when the flow graph is manipulated by various optimizations. A signed type makes those easy to detect.
Control flow edge information.
