Jingyue Wu f15b696b79 [NVPTX] Emit .pragma "nounroll" for loops marked with nounroll ... Summary: CUDA driver can unroll loops when jit-compiling PTX. To prevent CUDA driver from unrolling a loop marked with llvm.loop.unroll.disable is not unrolled by CUDA driver, we need to emit .pragma "nounroll" at the header of that loop. This patch also extracts getting unroll metadata from loop ID metadata into a shared helper function.
