* real.c (real_copysign): New function to implement libm's copysign.
* real.h (real_copysign): Prototype here.
* fold-const.c (tree_expr_nonnegative_p): The result of sqrt, sqrtf
and sqrtl can be negative, as sqrt(-0.0) = -0.0. Correct whitespace.
* builtins.c (fold_builtin_isascii, fold_builtin_toascii,
fold_builtin_isdigit): Add function prototypes.
(fold_builtin_copysign): New function to fold copysign, copysignf
and copysignl. Optimize copysign(x,x) as x. Evaluate copysign of
constant arguments at compile-time using real_copysign. Fold
copysign(X,Y) as fabs(X) if Y is always non-negative.
(fold_builtin_1): Correct minor whitespace/style issues. Call
fold_builtin_copysign for BUILT_IN_COPYSIGN{,F,L}.
* gcc.dg/builtins-41.c: New test case.
* gcc.dg/builtins-42.c: New test case.
