+ CodeBlock::m_numCalleeRegisters shouldn't also mean frame size, frame size needed for exit, or any other unrelated things
+ https://bugs.webkit.org/show_bug.cgi?id=124793
+
+ Reviewed by Mark Hahnenberg.
+
+ Now m_numCalleeRegisters always refers to the number of locals that the attached
+ bytecode uses. It never means anything else.
+
+ For frame size, we now have it lazily computed from m_numCalleeRegisters for the
+ baseline engines and we have it stored in DFG::CommonData for the optimizing JITs.
+
+ For frame-size-needed-at-exit, we store that in DFG::CommonData, too.
+
+ The code no longer implies that there is any arithmetic relationship between
+ m_numCalleeRegisters and frameSize. Previously it implied that the latter is greater
+ than the former.
+
+ The code no longer implies that there is any arithmetic relationship between the
