Use C11 *_TRUE_MIN macros where applicable.
C11 defines standard <float.h> macros *_TRUE_MIN for the least positive subnormal value of a type. Now that we build with -std=gnu11, we can use these macros in glibc. This patch replaces previous uses of the GCC predefines __*_DENORM_MIN__ (used in <float.h> to define *_TRUE_MIN), as well as *_DENORM_MIN references in comments. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). Also tested for powerpc that installed stripped shared libraries are unchanged by the patch. * math/libm-test.inc (min_subnorm_value): Use LDBL_TRUE_MIN, DBL_TRUE_MIN and FLT_TRUE_MIN instead of __LDBL_DENORM_MIN__, __DBL_DENORM_MIN__ and __FLT_DENORM_MIN__. * sysdeps/ieee754/dbl-64/s_fma.c (__fma): Refer to DBL_TRUE_MIN instead of DBL_DENORM_MIN in comment. * sysdeps/ieee754/ldbl-128/s_fmal.c (__fmal): Refer to LDBL_TRUE_MIN instead of LDBL_DENORM_MIN in comment. * sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c: Include <float.h>. (__nextafterl): Use LDBL_TRUE_MIN instead of __LDBL_DENORM_MIN__. * sysdeps/ieee754/ldbl-96/s_fmal.c (__fmal): Refer to LDBL_TRUE_MIN instead of LDBL_DENORM_MIN in comment.
