aurel32 9db3ba4db2 TCG x86/x86-64: use move with zero-extend for loads/stores ...

Starting with version 4.3, gcc returns the result of a function in
rax/eax/ax/al instead of rax/eax, depending of the return type. As
a consequence we should use a zero extend moe in TCG loads/stores.

See http://gcc.gnu.org/ml/gcc/2008-01/msg00052.html for more details.

A big thanks to malc who founds the problem and wrote the x86 patch.
