Austin Clements fe2feb978e runtime: poison the write barrier buffer during flushing 
Currently we reset the write barrier buffer before processing the
pointers in it. As a result, if there were any write barriers in the
code that processes the buffer, it would corrupt the write barrier
buffer and cause us to mark objects without later scanning them.

As far as I can tell, this shouldn't be happening, but rather than
relying on hope (and incomplete static analysis), this CL changes
wbBufFlush1 to poison the write barrier buffer while processing it,
and only reset it once it's done.

Updates #27993. (Unlike many of the other changes for this issue,
there's no need to roll back this CL. It's a good change in its own
right.)
