This improves readability and (theoretically) improves portability,
as _Ugly names are reserved.
This performs additional de-uglification, so all of these tests
follow the example of iterator.traits/empty.pass.cpp.

These tests for some guy's transparent operator functors were needlessly truncating their
double results to int. Preserving the doubleness makes compilers happier. I'm following
existing practice by adding an "// exact in binary" comment when the result isn't a whole number.
(The changes from 6 to 6.0 and so forth are stylistic, not critical.)
Fixes D27539.

Quite a few libcxx tests seem to follow the format:
#if _LIBCPP_STD_VER > X
// Do test.
#else
// Empty test.
#endif
We should instead use the UNSUPPORTED lit directive to exclude the test on
earlier C++ standards. This gives us a more accurate number of test passes
for those standards and avoids unnecessary conflicts with other lit
directives on the same tests.
