Turning on DUMP_PROPERTYMAP_STATS causes a build failure

Reviewed by Andreas Kling.

Source/JavaScriptCore:
Rewrote the property map statistics code because the old code wasn't building,
and it was also mixing numbers for lookups and insertions/removals.

New logging code records the number of calls to PropertyTable::find (finds) and
PropertyTable::get/PropertyTable::findWithString separately so that we can quantify
the number of probing during updates and lookups.

• jsc.cpp:
• runtime/PropertyMapHashTable.h:

(JSC::PropertyTable::find):
(JSC::PropertyTable::get):
(JSC::PropertyTable::findWithString):
(JSC::PropertyTable::add):
(JSC::PropertyTable::remove):
(JSC::PropertyTable::reinsert):
(JSC::PropertyTable::rehash):

• runtime/Structure.cpp:

(JSC::PropertyMapStatisticsExitLogger::PropertyMapStatisticsExitLogger):
(JSC::PropertyMapStatisticsExitLogger::~PropertyMapStatisticsExitLogger):

Source/WTF:
Added DEFINE_GLOBAL_FOR_LOGGING to allow running a destructor in logging code
that needs to be enabled in release builds (e.g. for JavaScriptCore).

• wtf/StdLibExtras.h:
