pr25541.ll - Was a regression test for a crash. Make a note and
autogenerate the tests.
bin_power.ll - Was essentially doing what UTC would do already, minus
one test where the assembly output is somewhat large, but the large
assembly output shouldn't be an issue with an autoupdate script and
isn't big enough to justify not including in my opinion.
This makes updating some tests easier for planned changes to LCSSA
preservation.
