Josh Bleecher Snyder f0c79caa13 runtime: move entry method from _func to funcInfo 
This will be required when we change from storing entry PCs in _func
to entry PC offsets, which are relative to the containing module.

Notably, almost all uses of the entry method were already called
on a funcInfo. Only Func.Entry incurs the additional module
lookup cost.

This makes Entry considerably slower, but it is probably
still fast enough in absolute terms that it is OK.
