[committed][nvptx] Unbreak build, add PTX_ISA_SM70

[Tom de Vries via Gcc-patches]

Hi,

With the commit "[nvptx] Choose -mptx default based on -misa" I introduced a
use of PTX_ISA_SM70, without adding it first.

Add it, as well as the corresponding TARGET_SM70.

Build for x86_64 with nvptx accelerator.

Committed to trunk.

Thanks,
- Tom
