Avoid constantly branching on m_table in getOffset

Summary Avoid constantly branching on m_table in getOffset
Maciej Stachowiak
Reported 2008-09-24 22:48:26 PDT
Profiles show that getOwnPropertySlot/getOffset spends a lot of time on the initial branch in getOFfset that checks if the table is null. Now that PropertyMap no longer has to fit into a cell, it could keep a table up to a certain limit inline and avoid this null check.
