fold-const.c (fold_unary): Test for availability of BUILT_IN_COS before simplifying REAL_PART(CEXPI)) to COS.
* 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.
