Revert r113439, which relaxed the requirement that loops containing calls cannot be unrolled. After some discussion,
...
there seems to be a better way to achieve the same effect.

Relax the "don't unroll loops containing calls" rule. Instead, when a loop contains a call, lower the
...
unrolling threshold to the optimize-for-size threshold. Basically, for loops containing calls, unrolling
can still be profitable as long as the loop is REALLY small.

Change tests from "opt %s" to "opt < %s" so that opt doesn't see the
...
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

of using llvm-as, now that opt supports this.

Add -unroll-allow-partial command line option that enabled the loop unroller to

partially unroll a loop when fully unrolling would not fit under the threshold.

Revamp the loop unroller, extending it to correctly update PHI nodes
...
in the presence of out-of-loop users of in-loop values and the trip
count is not a known multiple of the unroll count, and to be a bit
simpler overall. This fixes PR2253.
