Subject: Report out of memory if we cannot allocate memory for the deoptimization table.
X-Git-Tag: upstream/4.7.83~19236
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=945bd3e70cdb1f5e2585e346d816050eceaa96b9;p=platform%2Fupstream%2Fv8.git

Report out of memory if we cannot allocate memory for the deoptimization table.

Currently we pass a null pointer to memcpy. We will crash either way,
but going through FatalProcessOutOfMemory makes it clear what is going
on.
