+ [JSC] Unify indirectEvalExecutableSpace and directEvalExecutableSpace
+ https://bugs.webkit.org/show_bug.cgi?id=194339
+
+ Reviewed by Michael Saboff.
+
+ DirectEvalExecutable and IndirectEvalExecutable have completely same memory layout.
+ They have even the same structure. This patch unifies the subspaces for them.
