Make tcg_constant_folding do copy and constant propagation. It is a

This patch breaks QEMU on 32 bit hosts (tested on 386 Linux
and w32 hosts). Simply running qemu (BIOS only) terminates
with abort(). As the error is easy to reproduce, I don't provide
a stack frame here.
I can't reproduce, i386/Linux and win32 versions of i386, Sparc32 and
Sparc64 emulators work fine.
Maybe you have a stale build (bug in Makefile dependencies)?
Sorry, an important information was wrong / missing in my report.
It's not qemu, but qemu-system-x86_64 which fails to work.
I just tested it once more with a new build:
$ bin/x86_64-softmmu/qemu-system-x86_64 -L pc-bios
/qemu/tcg/tcg.c:1646: tcg fatal error
Abgebrochen
Cheers,
Stefan
