Move ROUNDING_TESTS_* out of math-tests.h.
Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the ROUNDING_TESTS_* macros for individual types out to their own sysdeps header. In the soft-float case where FE_TONEAREST is the only rounding mode macro defined, there is no need to define ROUNDING_TESTS_*; it is only necessary when rounding modes macros are defined that may not be supported at runtime. Thus, the ROUNDING_TESTS_* definitions for some configurations are just removed, not moved to new math-tests-rounding.h headers; the only architectures needing math-tests-rounding.h are those where the macros are defined in bits/fenv.h because of the possibility of a soft-float compilation using a hard-float glibc with the same ABI (i.e., ARM and RISC-V). The test-*-vlen*.h headers, by using #undef, do not yet follow typo-proof conventions (but they no longer implicitly rely on being included before math-tests.h, and this area can always be cleaned up further in future). Tested with build-many-glibcs.py. * sysdeps/generic/math-tests-rounding.h: New file. * sysdeps/generic/math-tests.h: Include <math-tests-rounding.h>. (ROUNDING_TESTS_float): Do not define here.
