Since r230164, in PR68330 combine ends up with a sign_extend of an
lshiftrt by some constant, and it does not know to morph that into a
zero_extract (the extend will always extend with zeroes). I think
it is best to let simplify-rtx always replace such a sign_extend by
a zero_extend, after which everything works as expected.

Some of the pa target macros rely on macros in emit-rtl.h and sdbout.c
