eq0/ne0.

This does not do wha you perhaps think it does. It looks for one of the
three atoms
"\mcntlzw", "isel", or "setbc\M". You should write
\m(cntlzw|isel|setbc)\M
or, if you need it to not capture (like in a scan-assembler-times)
\m(?:cntlzw|isel|setbc)\M

It may be easier to split the patch into two, where one part can get the
setbcr (the first, simplest function), and the rest stays the same.
Okay for trunk like that. Thanks!
