The Fortran front-end has a bug in which it uses "int" values for "size_t"
parameters.  I don't know why this isn't problem for all 64-bit 
architectures,
but GCN ends up with the data in the wrong argument register and/or 
stack slot,
and bad things happen.

This patch corrects the issue by setting the correct type.

	gcc/fortran/
	* trans-expr.c (gfc_trans_structure_assign): Ensure that
	integer_zero_node is of sizetype when used as the first
	argument of a call to _gfortran_caf_register.
	* trans-intrinsic.c (conv_intrinsic_event_query): Convert computed
	index to a size_t type.
	* trans-stmt.c (gfc_trans_event_post_wait): Likewise.
