2009-04-05tcg/x86_64: optimize register allocation orderaurel321-10/+9
The beginning of the register allocation order list on the TCG x86_64 target matches the list of clobbered registers. This means that when an helper is called, there is almost always clobbered registers that have to be spilled. The same way register %rsi and %rdi are at the top of the register allocation order list, while they can't be used for load/store operations. This means the data and/or address registers are very often %rsi and %rdi, and their values have to be spilled, and then moved back to another register. This patches changes to the allocation order to avoid those effects. It results in a 8% gain speed in qemu-x86_64 to compress a bzip2 file, and a 6% gain in qemu-system-mips64 to compile a small application.

2008-12-13TCG x86/x86-64: use move with zero-extend for loads/storesaurel321-0/+6
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.
