That way when declaring a test with DEF_TEST() macro, you don't have to
uniquify the test name because it might colide with the class it is
being testing.
For example, if you are testing SkBase64 and do:
DEF_TEST(SkBase64, reporter) {
}
That will generate an error because the macro will declare a function
named SkBase64 which colides with the type SkBase64.
By adding Test to the function name we avoid this problem.
Fixed the entries found with the following command line:
$ git grep "Test, r" | grep DEF
BUG=None
TEST=make tests && out/Debug/tests
