Teresa Johnson 1fd5bb9c53 Support for taking the max of module flags when linking, use for PIE/PIC ... Summary: Add Max ModFlagBehavior, which can be used to take the max of two module flag values when merging modules. Use it for the PIE and PIC levels. This avoids an error when we try to import from a module built -fpic into a module built -fPIC, for example. For both PIE and PIC levels, this will be legal, since the code generation gets more conservative as the level is increased. Therefore we can take the max instead of somehow trying to block importing between modules compiled with different levels.
