[Qemu-devel] tcg/arm fixes and improvements

[Aurelien Jarno]

This patch series fix a bug in div2/divu2 ops, implement setcond
and setcond2 ops and improve brcond/setcond by allowing immediate 
constants.

I have tested it using a modified version of target-mips/translate.c 
which includes setcond ops, and running mips-linux-user binaries. The 
first fixes was actually necessary to run such binaries. This has been
done with cpu-exec.c compiled with -O0 due to a bug (see my other mail).
