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.

Change these tests to feed the assembly files to opt directly, instead
...
of using llvm-as, now that opt supports this.

Rename ScalarEvolution's getIterationCount to getBackedgeTakenCount,
...
to more accurately describe what it does. Expand its doxygen comment
to describe what the backedge-taken count is and how it differs
from the actual iteration count of the loop. Adjust names and
comments in associated code accordingly.

Generalize support for analyzing loops to include SLE/SGE loop exit conditions

Sneaky, sneaky: move the -1 to the outside of the SMax. Reinstate the

optimization of SGE/SLE with unit stride, now that it works properly.
