Summary [JSC] Remove RareCaseProfile

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.
