Can you call this MTC1_HAZARD like the MFC0_HAZARD that got added
recently elsewhere? It's a pipeline hazard and not a synchronization
(which to me at least indicates some form of handshake) and it's also
specific to mtc1/dmtc1.

(also while this code appears to currently be 64-bit only, in the long
run the condition is wrong...)
