Pushed with some more fooling about. The "bit reversal" idea is not
a sufficient guide to picking values that will hit all the code checks.
For instance, I was seeing out-of-range warnings on one endianness and
not the other because on the other one the maxalign check rejected the
value first. I ended up manually tweaking the corruption patterns
until they hit all the tests on both endiannesses. Pretty much the
opposite of black-box testing, but it's not like our notions of line
pointer layout are going to change anytime soon.
I made some logic rearrangements in the C code, too.
