[patch] Simplify folding of a CALL_EXPR in fold_ternary

[Volker Reichelt]

The following patch simplifies the folding of a CALL_EXPR in fold_ternary
in fold-const.c by removing a superfluous if-statement and a couple of
temporaries.

Bootstrapped and regtested on i686-pc-linux-gnu.
Ok for mainline?

Regards,
Volker
