openmp, fortran: Fix up IFN_ASSUME call

Like in other spots in trans-openmp.cc that create a TARGET_EXPR, the
slot has to be created with create_tmp_var_raw, because gfc_create_var
adds the var to BLOCK_VARS and that ICEs during expansion because
gimple_add_tmp_var_fn has:
  gcc_assert (!DECL_CHAIN (tmp) && !DECL_SEEN_IN_BIND_EXPR_P (tmp));
assertion.  Also, both C/C++ ensure the argument to IFN_ASSUME has
boolean_type_node, it is easier if Fortran does that too.

	* trans-openmp.cc (gfc_trans_omp_assume): Use create_tmp_var_raw
	instead of gfc_create_var for TARGET_EXPR slot creation.  Create it
	with boolean_type_node and convert.
