So it looks like the you've got an ashift:SI where the shift amount of 
the result of an ashiftrt:HI -- note the difference in the modes.  That 
doesn't seem right.  It also looks like the indentation on the RTL 
pattern is wrong -- that ashiftrt is an argument of the ashift:SI, so it 
should line up with the (const_int 1) argument.

It looks like the same issue is repeated on the extractu pattern.  Which 
leads to a second comment.  I think the two patterns can be combined. 
There'a an "any_extend" iterator that you could use in place of the 
sign_extend/zero_extend.  And there's a "u" iterator that you can use in 
the output template to conditionally emit a "u".

The insertion, bclr, and bset patterns seem to be goofy on their modes 
in a similar way.

Presumably this is an if-then-else to deal with the case when the input 
value is zero?  Is there any way to use ctz/clz in combination with 
C[LT]Z_DEFINED_VALUE_AT_ZERO instead of ffs with a conditional?

More generally, can we avoid the UNSPECs in here by defining these 
operations in terms of ffs, clz, ctz?

Interesting truncation here?  Does the cv.cnt instruction really just 
write the result in QImode?  Or are you trying to express that the 
number of bits must be in the range 0..32 inclusive?  The former would 
make your code correct, the latter is better left to the generic VRP 
optimizer to discover.

Note I think there's a bitreverse opcode now.
