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.
