Web Inspector: debugger should be able to show variable types
https://bugs.webkit.org/show_bug.cgi?id=133395
Reviewed by NOBODY (OOPS!).
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.
