Handle oacc kernels with other directives
Mark directives with fn spec attributes to prevent them from acting as
optimization barrier.
gcc/
* builtin-attrs.def (DOT_DOT_r_r_r): Add DEF_ATTR_FOR_STRING.
(ATTR_FNSPEC_DOT_DOT_r_r_r_NOTHROW_LIST): Add DEF_ATTR_TREE_LIST.
* omp-builtins.def (BUILT_IN_GOACC_DATA_START)
(BUILT_IN_GOACC_ENTER_EXIT_DATA, BUILT_IN_GOACC_UPDATE): Use
DEF_GOACC_BUILTIN_FNSPEC instead of DEF_GOACC_BUILTIN.
