Pavel Kopyl 01afb3fb99 [NVPTX] Use by default 'sm_60' architecture when expanding %ptxas-verify macro.
Also get rid of explicitly specified '-march' values for old architectures.
This simplifies %ptxas-verify statements.
After the change, we can potentially miss cases where a new functionality
is added to the architecture without appropriate checks in the
backend. On the other hand, this is mostly true for old architectures
that have been thoroughly tested.
