[PATCH] D51042: [NVPTX] Remove ftz variants of cvt with rounding mode

This is a surprise. PTX ISA does not mention that .ftz is not applicable to `cvt.*.f16.*` instructions. 
Is it only `cvt` that does not support .ftz or does it impact other instructions?  PTX spec has add/sub/mul/fma/set/setp instructions that support f16 and have .ftz variant.
