This commit fixes llvm-cov's function coverage metric by using the number of executed functions instead of the number of fully covered functions.

If we have multiple coverage counts for the same segment, we need to
add them up rather than arbitrarily choosing one. This fixes that and
adds a test with template instantiations to exercise it.

This splits the logic for actually looking up coverage information
from the logic that displays it. These were tangled rather thoroughly
so this change is a bit large, but it mostly consists of moving things
around. The coverage lookup logic itself now lives in the library,
rather than being spread between the library and the tool.

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.
