38c59de6b1 llvm-cov: Use the number of executed functions for the function coverage metric.
This commit fixes llvm-cov's function coverage metric by using the number of executed functions instead of the number of fully covered functions.

aacc919bfd llvm-cov: Combine segments that cover the same location
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.

9eb38163a5 llvm-cov: Disentangle the coverage data logic from the display (NFC)
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.

65b3fca21f 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.
