nvptx backend: add -mgomp option and multilib
Since OpenMP offloading requires both soft-stacks and "uniform SIMT", both
non-traditional codegen variants, I'm building a multilib variant with those
enabled. This patch adds option -mgomp which enables -msoft-stack plus
-muniform-simt, and builds a multilib with it.
* config/nvptx/nvptx.c (nvptx_option_override): Handle TARGET_GOMP.
* config/nvptx/nvptx.opt (mgomp): New option.
* config/nvptx/t-nvptx (MULTILIB_OPTIONS): New.
* doc/invoke.texi (mgomp): Document.
