Re-enable the int32 fast path for ShiftRightLogical, but account for Maglev's missing signed/unsigned representation tracking by a) removing rhs==0 as the identity value (a shift by 0 is still a signed-unsigned conversion) and b) deoptimizing if the result cannot be converted to a non-negative smi. Note this is not a deopt loop, since a non-smi result will change the feedback to kSignedSmallInputs (from kSignedSmall). To fix this properly, we should track signed/unsigned representations and convert the result to a heap number if it doesn't fit within smi range.

We've previously used JSFunction::GetActiveTier, which looks at JSFunction::code to determine the active tier. However, that may diverge from the actually active tier (i.e. the calling frame type), e.g. when Turbofan code is available but we haven't yet tiered up because we're stuck in a longrunning loop. With this CL, we determine the caller code_kind by splitting the BytecodeBudgetInterrupt runtime function up into _Ignition, _Sparkplug, and _Maglev variants s.t. the tier is passed implicitly without extra overhead at runtime.

Add an enum in the jump buffer to represent the state of the stack: active, suspended, or retired. Update the state on stack switch and check that they are consistent. The previous method relied on comparing the current stack pointer with the bounds of the stack, which was not reliable because the upper bound of the native stack is not known precisely.

Philip Chimento authored
This test somehow ended up inside an assertThrows arrow function, after the expression that was supposed to throw -- so it never got executed (and the expectation was slightly off.) This moves the test outside the arrow function so it gets executed, and fixes the expectation. Justification for changing the expectation: rab is [0, 1, 2, 3, ... 9], and length_tracking_ta_with_offset2 has an offset of 2, so it is [2, 3, ...]. During the loop, after 2 iterations which have produced [2, 3], we resize the buffer so the array has length 0. Therefore, the iteration ends after producing [2, 3], not [3, 4].
