Please review. Note: I am not a committer. I deleted the earlier CL because it
was incomplete.

for f in $(find third_party/tcmalloc/chromium/src/ | grep -v \.svn); do sed -i
's/ptrdiff_t/std::ptrdiff_t/g' $f; done

I've opened http://codereview.chromium.org/7046043 and posted the tryjobs. Will
submit if/once they pass. Please consider using the Linux and Win trybots when
patching tcmalloc.

Compilation passed on the bots.
LGTM, awaiting the tree to open.
