2a0c5d7867 coverage: remove empty mapping regions
This patch removes the empty coverage mapping regions.
Those regions were produced by clang's old mapping region generation 
algorithm, but the new algorithm doesn't generate them.

9c8d526a9f Add code coverage mapping data, reader, and writer.
This patch implements the data structures, the reader and
the writers for the new code coverage mapping system. 
The new code coverage mapping system uses the instrumentation
based profiling to provide code coverage analysis.
