Add more thorough generated tgmath.h test.
This patch adds a more thorough test of tgmath.h macros, verifying both the return type and the function called for all the cases of valid argument types. (Cases with current problems - I've just filed four bugs - are disabled or omitted pending fixing those problems.) The test uses a Python generator (works with both Python 2 and 3) to generate a C file which is then built and run as a test in the usual way (and that C file includes its own dummy definitions of libm functions similar to existing tgmath.h tests). The motivation is to make it easier to add tests of tgmath.h for _Float128 when adding tgmath.h support for that type; the _FloatN / _FloatNx support is present in the script, but disabled until the tgmath.h support is written. Tested for x86_64, and for arm to check things in the long double = double case. (In that case, it's OK to call either double or long double functions when the selected type is double or long double, as long as the return type of the macro is exactly correct.) * math/gen-tgmath-tests.py: New file. * math/Makefile [PYTHON] (tests): Add test-tgmath3. [PYTHON] (generated): Add test-tgmath3.c. [PYTHON] (CFLAGS-test-tgmath3.c): New variable. [PYTHON] ($(objpfx)test-tgmath3.c): New rule.

# other), with interchange types being preferred to standard types
