Fix IC handler cache clearing for JSBuiltinsObject
...
The clearing mechanism relies on comparing the cached handler with the installed handler. If we try to preserve monomorphism by pretending that the IC was in uninitialized state, then it will go premonomorphic first, which means on the next miss there's no installed handler available to compare against. Instead, pretend it was premonomorphic, so the comparison will happen right away, will fail as it should, and the cached handler will be cleared.
Thanks to Weiliang for starting the investigation that led to this.

[turbofan] Remove int32 narrowing during typed lowering.
...
With Int32Add we lose the int/uint distinction, so later, in simplified lowering we can make a wrong decision. E.g., see the attached test case, where we lower NumberAdd -> Int32Add because inputs are Uint32, but during simplified lowering we change the inputs to Int32, so we get a wrong result.
Simplified lowering will lower the NumberAdd operations anyway, so we should lose performance.
