By replacing usage of the IsNotArrayIndex bit with IsNotIntegerIndex, we get back one bit that we can use to increase the number of hash bits stored. The price is that strings that represent array/integer indices beyond the cacheable range will have to be scanned more often, but these strings should be rare, and we expect that the additional hash bit is more worthwhile to have.

There is a copy of the pointer decompression logic in TypedArrayBuiltinsAssembler::SetJSTypedArrayOnHeapDataPtr, which was not updated for the new ("smi-corrupting") pointer compression scheme: it erroneously used a sign-extending cast from compressed to full representation. This causes incorrect values to be computed when the heap size can grow beyond 2GB.

port 9d3dc6f2 https://crrev.com/c/1914218 Original Commit Message: FunctionEntry StackChecks is one of the two cases where we generate a StackCheck bytecode. In these cases, we do stack check against the js limit (not to be confused with the real js limit). Their purpose is to be able to interrupt the running code. We can omit the FunctionEntry StackCheck by embedding its code into the InterpreterEntryTrampoline builtin. We save one bytecode per interpreted function. This change has rippling effects for optimized code, as well as the deoptimizer.
