See test.  Judging from PR 1278, at the time the test was committed, the
generated code was apparently doing stores directly into the return value

That object is initialized using [4 x i8] which breaks the test.  I believe
this change preserves the original point of the test.

Of course it would be better for the code to do stores directly into the
return aggregate, but that is not what happens at -O0; the llvm optimizers
seem to do that on x86 but not on ppc32, possibly because of the explicit

Fix this code to correctly handle loops with multiple exits. Until
now, this hasn't mattered, because ScalarEvolution hasn't been able
to compute trip counts for loops with multiple exits. But it will
soon.
