builtins.c (fold_builtin_cosh): New.
* builtins.c (fold_builtin_cosh): New.
(fold_builtin_1): Use it.
* fold-const.c (negate_mathfn_p): Add llround, lround, round,
trunc to the list of "odd" functions. Also add llrint, lrint,
rint and nearbyint when flag_rounding_math is false.
testsuite:
* gcc.dg/torture/builtin-symmetric-1.c: Add more cases.
