Subject: X87: Introduce LiteralsArray to hide it's implementation.
X-Git-Tag: upstream/4.7.83~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=377d860d99c04e3485cf67ee9ea8c646547114c2;p=platform%2Fupstream%2Fv8.git

X87: Introduce LiteralsArray to hide it's implementation.

port d8cdd6956a04cfcf03159ef7802c44838eee3146 (r31000).

original commit message:

    The LiteralsArray will soon hold a type feedback vector. Code treats it as an
    ordinary fixed array, and needs to stop that.
