Description

MIPS: Improve write barriers in optimized code. Port r21630 (a21ff10) Original commit message: Use a cheaper RecordWriteForMap() to update the write barrier for maps. And skip the value check in RecordWriteField() when we statically know that the value is in new space (and therefore has "pointers to here are interesting" flag set). BUG=
