  [Driver] -fstack-size-section: pass -stack-size-section to backend for LTO

The option does not change IR but affect object file generation. Without a
backend option the option is a no-op for in-process ThinLTO.

The problem is known and there are many options similar to -fstack-size-section.
That said, -fstack-size-section has relatively wider adoption, so it probably
makes sense to have custom code for it.
