Make CoverageMapping easier to create, so that we can write targeted
unit tests for its internals, and add a some infrastructure to write
these tests. Finally, add a simple unit test for basic functionality.

This time we use a helper to format the assertion so we can just use
ASSERT_TRUE instead of relying on ASSERT_EQ being able to deal with
conversions between enum types.
This reverts r229496, re-applying r229473.

The llvm-level tests for coverage mapping need a binary input file,
which means they're hard to understand, hard to update, and it's
difficult to add new ones. By adding some unit tests that build up the
coverage data structures in C++, we can write more meaningful and
targeted tests.
