cmd/compile: revert most of CL 349169

Browse source 
The method of using references to dictionaries to hold methods
live during linker deadcode elimination wasn't working very well.
I implemented a new scheme in the CL below this, so this CL strips
out the old method.

The new method has the added benefit of having 0 runtime overhead
(unlike the stuff we're ripping out here, which does have a small overhead).

Update #48047
