Fix Clang warning:
| warning: definition of implicit copy constructor for 'ValueArray2<bool, bool>'
| is deprecated because it has a user-declared copy assignment operator [-Wdeprecated]
Add the possibility of specifying the name in type parameterized tests.
Similar to how the last parameter of INSTANTIATE_TEST_CASE_P allows to override the name for (non-type) parametrized tests, this adds the possibility of adding a parameter to INSTANTIATE_TYPED_TEST_CASE_P. The argument has to be a class, which contains a static templated function GetName<T>(int), returning the name for type T.

Fix Theta(N^2) memory usage of EXPECT_EQ(string) when the strings don't match.
The underlying CalculateOptimalEdits() implementation used a simple
dynamic-programming approach that always used N^2 memory and time. This meant
that tests for equality of large strings were ticking time bombs: They'd work
fine as long as the test passed, but as soon as the strings differed the test
would OOM, which is very hard to debug.
I switched it out for a Dijkstra search, which is still worst-case O(N^2), but
in the usual case of mostly-matching strings, it is much closer to linear.

GTEST_TEST_FILTER_ENV_VAR_ was used to specify an environment variable to obtain
the default test filter from. By default it was unset which broke
"--test_filter" for bazel. This CL eliminates GTEST_TEST_FILTER_ENV_VAR_ and
explicitly obtains the default test filter from the environment variable
TESTBRIDGE_TEST_ONLY if it exists.
This canonicalizes demangled names by omitting a nested inline namespace within namespace std if the name of the nested namespace begins with a double underscore. This improves compatibility with libc++.
