[nvptx] Apply vector-partitionable routines workaround to default vl

Make "[nvptx] Force vl32 if calling vector-partitionable routines" work as well
if vector length is set by modifying PTX_DEFAULT_VECTOR_LENGTH.

2019-01-12  Tom de Vries  <tdevries@suse.de>

	* config/nvptx/nvptx.c (nvptx_goacc_validate_dims_1): In offloading
	region calling vector-partitionable routine, set default_vector_length
	to WARP_SIZE.
