Fix lgamma*, log10* and log2* results [BZ #21171]
lgamma(-x) should return +Inf and raise divide-by-zero. log10(+-0) and log2(+-0) should return -Inf and raise divide-by-zero. Tested on powerpc, powerpc64, powerpc64le and x86_64. [BZ #21171] * sysdeps/ieee754/dbl-64/e_lgamma_r.c (__ieee754_lgamma_r): Return +Inf and raise divide-by-zero when x is negative. * sysdeps/ieee754/flt-32/e_lgammaf_r.c (__ieee754_lgammaf_r): Likewise. * sysdeps/ieee754/ldbl-128/e_lgammal_r.c (__ieee754_lgammal_r): Likewise. * sysdeps/ieee754/dbl-64/e_log10.c (__ieee754_log10): Return -Inf and raise divide-by-zero when x = +-0. * sysdeps/ieee754/dbl-64/e_log2.c (__ieee754_log2): Likewise. * sysdeps/ieee754/flt-32/e_log10f.c (__ieee754_log10f): Likewise. * sysdeps/ieee754/flt-32/e_log2f.c (__ieee754_log2f): Likewise. * sysdeps/ieee754/ldbl-128/e_log10l.c (__ieee754_log10l): Likewise. * sysdeps/ieee754/ldbl-128/e_log2l.c (__ieee754_log2l): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_log10l.c (__ieee754_log10l): Likewise. * sysdeps/ieee754/ldbl-128ibm/e_log2l.c (__ieee754_log2l): Likewise.
