Did 1 & 2 of @eli.friedman's suggestions.

After a quick look, I didn't see how to do #3 and left it out. We may want to give it a try separately as it may be a general improvement to the known bits infrastructure.

@nikic, could you do a measurement of the latest patch, please?

Then we can decide if we want to pursue either the cut-off idea or somehow expose the precise vs. less precise gep analysis.
