How to navigate around the source tree?

[Matthew Pickering]

Hi,

The module rework has broken my workflow.

Now my tags file is useless for jumping for modules as there are
multiple "Utils" and "Types" modules. Invariable I am jumping to the
wrong one. What do other people do to avoid this?

Can we either revert these changes or give these modules unique names
to facilitate that only reliable way of navigating the code base.
Perhaps `HsUtils` and `StgUtils` would be appropriate to disambiguate
`Hs/Utils` and `StgToCmm/Utils`.

Cheers,

Matt
