Hans Wennborg 4d48c3f1aa LazyValueInfo: Actually re-visit partially solved block-values in solveBlockValue() ... If solveBlockValue() needs results from predecessors that are not already computed, it returns false with the intention of resuming when the dependencies have been resolved. However, the computation would never be resumed since an 'overdefined' result had been placed in the cache, preventing any further computation. The point of placing the 'overdefined' result in the cache seems to have been to break cycles, but we can check for that when inserting work items in the BlockValue stack instead. This makes the "stop and resume" mechanism of solveBlockValue() work as intended, unlocking more analysis. Using this patch shaves 120 KB off a 64-bit Chromium build on Linux. I benchmarked compiling bzip2.c at -O2 but couldn't measure any difference in compile time. Tests by Jiangning Liu from r215343 / PR21238, Pete Cooper, and me.
