I've tried the pr108947.c testcase, but I see no differences in the assembly
before/after the patch (but dunno if I'm using the right options).
The pr109040.c testcase from the patch I don't see the expected zero
extension without the patch and do see it with it.
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:

PR target/109040
* 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.dg/pr108947.c: New test.
* 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.
