commit r12-7329-gbc91cb8d8cf1d4abbb74fb69d918071e1801fd77
Author: Tobias Burnus <tobias@codesourcery.com>

nvptx: Add -mptx=6.0
Currently supported internally are 3.1, 6.0, 6.3 and 7.0.
However, -mptx= supports 3.1, 6.3, 7.0 – but not the internal default 6.0.
Add -mptx=6.0 for consistency.
Tested on nvptx.
gcc/ChangeLog:
* config/nvptx/nvptx.opt (mptx): Add 6.0 alias PTX_VERSION_6_0.
* doc/invoke.texi (-mptx): Update for new values and defaults.
