This patch moves the HIGH_ORDER_BIT_IS_SET_FOR_SNAN macro from being defined or undefined to the preferred convention of always being defined, to either 0 or 1, so allowing typo-proof tests with #if. The macro is moved from math_private.h to a new header nan-high-order-bit.h to make it easy for all architectures to define, either through the sysdeps/generic version of the header or through providing their own version of the header, without needing #ifndef in the generic math_private.h to give a default definition. The move also allows the macro to be used without needing math_private.h to be included; the immediate motivation of this patch is to allow tests to access this information (to know what kinds of NaNs 0 is a valid payload for) without needing to include math_private.h. Existing C level rather than preprocessor conditionals at all, but this patch does not make such a change). Tested for x86_64 and x86 (testsuite); also verified for x86_64, x86, mips64 and powerpc that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/nan-high-order-bit.h: New file. * sysdeps/hppa/nan-high-order-bit.h: Likewise. * sysdeps/mips/nan-high-order-bit.h: Likewise. * sysdeps/hppa/math_private.h: Remove file. * sysdeps/mips/math_private.h (HIGH_ORDER_BIT_IS_SET_FOR_SNAN): Do not define here. * sysdeps/ieee754/dbl-64/s_issignaling.c: Include <nan-high-order-bit.h>.
