-----------
[JavaScriptCore] Absence PropertyCondition does not consult non-reified
static property tables

rdar://176792596
Reviewed by Yusuke Suzuki.
This patch modifies the Absence case for
PropertyCondition::isStillValidAssumingImpurePropertyWatchpoint
to consult the non-reified static property table if the property isn't present
in the property table.
This prevents the Abstract Interpreter from misfolding GetById.
