nvptx: Add -mptx=6.0

Browse source 
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.
