builtins.c (expand_builtin_pow, [...]): Remove uses of dconst3, dconstsqrt2, dconstthird, dconste and/or dconst10.
* builtins.c (expand_builtin_pow, fold_builtin_cabs,
fold_builtin_sqrt, fold_builtin_cbrt, fold_builtin_logarithm,
fold_builtin_hypot, fold_builtin_pow): Remove uses of dconst3,
dconstsqrt2, dconstthird, dconste and/or dconst10.
* config/i386/i386.c (ix86_emit_swsqrtsf): Likewise.
* emit-rtl.c (dconst3, dconst10, dconstm2, dconstthird,
dconstsqrt2, dconste): Delete.
(init_emit_once): Likewise. Simplify initializing dconstm1.
Constify variable.
* real.c (get_real_const): New.
* real.h (dconst3, dconst10, dconstm2, dconstthird,
dconstsqrt2, dconste): Delete.
(real_value_const, get_real_const): New.
