builtins.c (real_dconstp, [...]): New, split out from fold_builtin.
* builtins.c (real_dconstp, fold_builtin_logarithm,
fold_builtin_exponent): New, split out from fold_builtin. Also
generalize to add log2, log10, exp2 and exp10/pow10 equivalents.
* emit-rtl.c (dconst3, dconst10, dconstthird): New.
(init_emit_once): Initialize new dconsts, use ARRAY_SIZE in lieu
of hardcoded array size.
* fold-const.c (fold): Add cases for exp2, exp10 and pow10.
(tree_expr_nonnegative_p): Likewise.
* real.h (dconst3, dconst10, dconstthird): New.
testsuite:
* gcc.dg/torture/builtin-explog-1.c: New testcase.
