Convert (ffs(val) - 1) to ctz32(val)
This commit was generated mechanically by coccinelle from the following
semantic patch:
@@
expression val;
@@
- (ffs(val) - 1)
+ ctz32(val)
The call sites have been audited to ensure the ffs(0) - 1 == -1 case
never occurs (due to input validation, asserts, etc). Therefore we
don't need to worry about the fact that ctz32(0) == 32.
