[Driver] Pass -plugin-opt=O2 for -Os -Oz and -plugin-opt=O1 for -Og
Fixes PR42445 (compiler driver options -Os -Oz translate to
-plugin-opt=Os (Oz) which are not recognized by LLVMgold.so or LLD).
The optimization level mapping matches
CompilerInvocation.cpp:getOptimizationLevel() and SpeedLevel of
PassBuilder::OptimizationLevel::O*.
-plugin-opt=O* affects the way we construct regular LTO/ThinLTO pass
manager pipeline.
