  [JSC] Move BaselineJITExecutionCounter to BaselineJITData
https://bugs.webkit.org/show_bug.cgi?id=280169
rdar://136482703

Reviewed by Yijia Huang.

This patch moves BaselineJITExecutionCounter from CodeBlock to
BaselineJITData as it is only used by Baseline JIT. Also accessing
this from Baseline JIT is frequently happening (loop_hint etc.), so
using BaselineJITData makes it better than loading CodeBlock from the
stack and accessing this field.
