Dimitry Andric 5c47cd667d Pull in r180121 from upstream llvm trunk: 
LoopVectorizer: Fix 15830. When scalarizing and unrolling stores make
  sure that the order in which the elements are scalarized is the same
  as the original order.
  This fixes a miscompilation in FreeBSD's regex library.

This should fix lib/libc/regex/regcomp.c at -O3 with clang 3.3 r178860
on CPUs with SSE.  Before this change, the vectorizer could incorrectly
rearrange the second loop in computejumps(), leading to possibly invalid
entries in the re_gets::charjump table.

The net result was that for example "sed s/@CC@/foo/" failed to work
correctly, leading to trouble with many configure scripts.
