Use generic macros for lgamma_r function aliases.
Continuing the use of generic macros for defining libm function aliases, in preparation for adding more _FloatN / _FloatNx function names, this patch makes the lgamma_r functions use such macros. declare_mgen_alias_r becomes a standard macro in math-type-macros.h instead of being locally defined in w_lgamma_r_templace.c. This in turn must be defined by each math-type-macros-<type>.h. Rather than providing an unused default in math-type-macros.h, that header is made to give an error if math-type-macros-<type>.h failed to define declare_mgen_alias or declare_mgen_alias_r. The compat lgamma_r wrappers are updated similarly. The ldbl-opt versions are removed as no longer needed. Tested for x86_64, and with build-many-glibcs.py. Installed stripped shared libraries are unchanged except for powerpc64le (where the usual issue applies that an ldbl-opt long double function previously used long_double_symbol unconditionally and now the symbol versions on powerpc64le mean weak_alias is used instead, resulting in the same symbol versions in the final shared library but still enough difference in the input objects for that library not to be byte-identical). * sysdeps/generic/math-type-macros.h [!declare_mgen_alias]: Give error. Remove default definition of declare_mgen_alias. [!declare_mgen_alias_r]: Likewise. * sysdeps/generic/math-type-macros-double.h [!declare_mgen_alias_r] (declare_mgen_alias_r): New macro. * sysdeps/generic/math-type-macros-float.h [!declare_mgen_alias_r] (declare_mgen_alias_r): Likewise. * sysdeps/generic/math-type-macros-float128.h [!declare_mgen_alias_r] (declare_mgen_alias_r): Likewise. * sysdeps/generic/math-type-macros-ldouble.h [!declare_mgen_alias_r] (declare_mgen_alias_r): Likewise. * math/w_lgamma_r_template.c (declare_mgen_alias_r_x): Remove macro. (declare_mgen_alias_r_s): Likewise. (declare_mgen_alias_r): Likewise. * math/w_lgamma_r_compat.c: Include <libm-alias-double.h>. (lgamma_r): Define using libm_alias_double_r. * math/w_lgammaf_r_compat.c: Include <libm-alias-float.h>. (lgammaf_r): Define using libm_alias_float_r. * math/w_lgammal_r_compat.c: Include <libm-alias-ldouble.h>. (lgammal_r): Define using libm_alias_ldouble_r. * sysdeps/ieee754/ldbl-opt/w_lgamma_r_compat.c: Remove file. * sysdeps/ieee754/ldbl-opt/w_lgammal_r_compat.c: Likewise.
