Subject: [PATCH 1/2] [clang][nvlink-wrapper] Add support for opt-remarks
command line options
This patch adds support for optimization record command line options to
clang-nvlink-wrapper, fixing an issue where using -fsave-optimization-record
with CUDA offloading would fail with "Unknown command line argument
'opt-remarks-format=yaml'".
