[cuda] Ignore "TLS unsupported by target" errors for host variables during device compilation.

During device-side CUDA compilation clang currently complains about
all TLS variables, regardless of whether they are __host__ or
__device__.

This patch suppresses "TLS unsupported" errors for host variables
during device compilation and for device variables during host
compilation.
