[nvptx] Update insufficient launch message for variable vector_length
Update message in nvptx libgomp plugin about insufficient resources to launch kernel, to accommodate for the fact the vector_length can now be variable. 2019-01-12 Tom de Vries <tdevries@suse.de> * plugin/plugin-nvptx.c (nvptx_exec): Update insufficient hardware resources diagnostic.
