Seems my cross defaulted to 32-bit compilation, reproduced it with
additional -mabi=lp64 -march=rv64gv even on the pr108947.c test.
So, let's include that test in the patch too:

* combine.cc (simplify_and_const_int_1): Compute nonzero_bits in
word_mode rather than mode if WORD_REGISTER_OPERATIONS and mode is
smaller than word_mode.
* simplify-rtx.cc (simplify_context::simplify_binary_operation_1)
<case AND>: Likewise.

* gcc.c-torture/execute/pr109040.c: New test.
Bootstrap of the v3 patch has completed. Regression testing is still
spinning. It should be done and waiting for me when I wake up in the
morning.
It's still okay for trunk (of course) if the bootstrap doesn't fail (of
course). Thanks guys!
Bootstrap was successful with v3, but there's hundreds of testsuite
failures due to the simplify-rtx hunk. compile/20070520-1.c for example
when compiled with: -O3 -funroll-loops -march=rv64gc -mabi=lp64d
Thursdays are my hell day. It's unlikely I'd be able to look at this at
all today.
