RareCareProfile is only used for add, to_this, sub and mod, while we are allocating it for all bytecodes having slowcases in JIT.
And since each RareCaseProfile has 8 bytes, this is too large for this rare case counter.
We should do some of these things.
1. We should consider putting very small counter (uint8_t or less) in Metadata for these opcodes.
2. And/Or we should put this counter in IC's data structure.
