[JSC] Inline MapIteratorKey / MapIteratorValue / SetIteratorKey
https://bugs.webkit.org/show_bug.cgi?id=302441
rdar://164606199
Reviewed by Yijia Huang.
This patch simply inlines MapIteratorKey / MapIteratorValue / SetIteratorKey
operations in DFG / FTL as they are super simple operations.
We also clean up MapStorage mechanism.
1. We should not allocate a heap memory in MapStorage. Let's just peek
the current storage (it may be JSEmpty).
2. We should always set iterator with the current storage so we can make
::next operation faster.
