Subject: Update 4.8.1 to 4.8.3.

My previous drop was the wrong version. The platform mingw is
currently using 4.8.3, not 4.8.1 (not sure how I got that wrong).

From ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.3/gcc-4.8.3.tar.bz2.

Bug: http://b/26523949

+# It's meant to be easy to modify the heuristics used to select the
+# next patch to try by adding to or rearranging the patches listed in

+#
+# A nifty improvement would be to record known ranges of failure as
+# ranges, and then pick revisions just before and just after the range.
