if an address of a register parameter is taken, create immediately a backing store
instead of moving it from the argument type (where it might not exist if no
value type was built)

  most parts was already here)
- only remap Sel if we change the value parameter type in lower_dw.c

  of functions if possible: this fixes abi_null_mode_proj

The old code was fundamental broken, because it
- changes the cls of a node WITHOUT changing a following be_Keep
- produced the xmm0 reload BEFORE the Keep -> both nodes define xmm0

The new code handles some simple cases even more gracefully.

- BSF/BSR cannot do 16 bit AM in our model, because they only set the lower 16 bits of the destination register then.
- Rename gen_unop_dest() to gen_unop_AM().
