target-i386: Don't left shift negative constant 
Left shift of negative values is undefined behavior. Detected by clang:
qemu/target-i386/translate.c:2423:26: runtime error:
left shift of negative value -8

This changes the code to reverse the sign after the left shift.

Backports commit 712b4243c761cb6ab6a4367a160fd2a42e2d4b76 from qemu
