pragma: respect pragma in lambda functions
Commit Message
In g:01ad8c54fdca we started supporting target pragma changes
that are primarily caused by optimization option. The same can happen
in the opposite way and we need to check for changes both
in optimization_current_node and target_option_current_node.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Ready to be installed?
Thanks,
Martin
