Add --print-module-resolution debug option.

This patch adds the --print-module-resolution debug flag, to print out the module
currently being resolved along with its depth in the "use" tree.

Modules are resolved according to a postorder traversal of the "use" tree.  The "use" tree
is the "use" graph (which can contain cycles) with back-edges removed.

[tested on compflags/ (std)]
