For more types to be profiled, we need better coverage.
Created attachment 234384 [details] patch More operations are now being recorded by the profile_types_with_high_fidelity opcode. Specifically: function parameters, function return values, function 'this' value, get_by_id, get_by_value, resolve nodes, function return values at the call site. Added more flags to the profile_types_with_high_fidelity opcode so more focused tasks can take place when the instruction is being linked in CodeBlock. Re-worked the type profiler to search through character offset ranges when asked for the type of an expression at a given offset. Removed redundant calls to Structure::toStructureShape in HighFidelityLog and TypeSet by caching calls based on StructureID.
Comment on attachment 234384 [details] patch I will land it.
