+        Added a regular expression tracing facility.  This tracing is connected
+        to jsc.  Every compiled regular expression object is added to a list.
+        When the process exits, each regular expression dumps its pattern,
+        JIT address, number of times it was executed and the number of matches.
+        This tracing is controlled by the macro ENABLE_REGEXP_TRACING in
+        wtf/Platform.h.
