Andrew Kelley e565ff305a CLI: revert -l behavior 
chicken out and make -l match the status quo behavior, where it looks
for dynamic libraries and then falls back to static libraries.

library resolution is still done in the CLI now though, and these
options are added:

-search_static_first           Search for static libs in all library search
                               paths, then dynamic libs.
-search_dylibs_only            Only search for dynamic libs.
-search_static_only            Only search for static libs.

this matches the already existing options below:

-search_paths_first            For each library search path, check for dynamic
                               lib then static lib before proceeding to next path.
-search_dylibs_first           Search for dynamic libs in all library search

So, it is still possible to get the strict behavior by passing
`-search_dylibs_only` or `-search_static_only`.

This commit also makes -dynamic and -static affect the preferred link
mode and search strategy.
