[XLA:GPU] Warn if ptxas or the driver JIT has known bugs.

We try to compile ptx->sass using ptxas, and fall back to the driver JIT
only if this fails.  So we only warn about a bad driver JIT version if
we actually use the driver to compile our ptx.

This change also quiets a LOG(INFO) to a VLOG(1) in cuda_diagnostics.cc
so we don't spit out the full contents of the driver file when we query
it.
