        * fold-const.c (fold_unary) <REAL_PART>: Test for availability of
        BUILT_IN_COS before simplifying REAL_PART(CEXPI)) to COS.
        <IMAG_PART>: Likewise, check for availability of BUILT_IN_SIN.
        * builtins.c (fold_builtin_sincos): Check for TARGET_C99_FUNCTIONS
        before canonicalizing sincos to cexpi.
        (fold_builtin_cexp): Likewise, for canonicalizing cexp to cexpi.

is too conservative in the sense that we can expand __builtin_cexpi if
either TARGET_HAS_SINCOS or TARGET_C99_FUNCTIONS.
