reduced test case in plain C

Reduced test case.  This one ICEs both 4.4 and 4.3 but not 4.5.

Using the reduced test case a new bisection of trunk identified r147577 as the
fix for this bug.  r147577 added support for PRE_DEC in NEON memory operands,
which makes sense given the pre_dec in the insn that gcc complains about.

r147577 applies easily to 4.4 and eliminates the ICE.  I'll start a full
bootstrap and regression test on this combo in a few minutes.
