[LoopUnroll] Switch the default value of -unroll-runtime-epilog back to its original value.

As agreed in post-commit review of r265388, I'm switching the flag to
its original value until the 90% runtime performance regression on
SingleSource/Benchmarks/Stanford/Bubblesort is addressed.

Adds the ability to use an epilog remainder loop during loop unrolling and makes

this the default behavior.

[LoopUnrollRuntime] Clean up a predicate.

Clean up a predicate I added in r229731, fix the relevant comment and
add a test case.  The earlier version is confusing to read and was also
buggy (probably not a coincidence) till Alexey fixed it in r233881.
