llvmpipe: switch to using dynamic stack allocation instead of registers
with mutable vars we don't need to follow the phi nodes. meaning that control flow becomes trivial as we don't have scan the rest of the tgsi to figure out the variable usage anymore. futhermore the memory2register pass promotes alloca/store/load to registers while inserting the right phi nodes. so we get simplicity and performance.
