WebAssembly: Don't store MachineFunction in MachineFunctionInfo

Soon it will be disallowed to depend on MachineFunction state in the
constructor. This was only being used to get the MachineRegisterInfo
for an assert, which I'm not sure is necessarily worth it. I would
think any missing defs would be caught by the verifier later instead.
