gcov: add support for gcc 4.7 gcov format
The gcov in-memory format changed in gcc 4.7. The biggest change, which requires this special implementation, is that gcov_info no longer contains array of counters for each counter type for all functions and gcov_fn_info is not used for mapping of function's counters to these arrays(offset). Now each gcov_fn_info contans it's counters, which makes things a little bit easier. This is heavily based on the previous gcc_3_4.c implementation and patches provided by Peter Oberparleiter. Specially the buffer gcda implementation for iterator.
