CF frontend: Canonicalize debug local info

IRBuilder#readRegister(int, ValueType) checks that local info in the
current definition of a register is reference-equal to the local info
returned by getIncomingLocal(). The CF frontend should canonicalize the
DebugLocalInfo objects accordingly.

This bug was found when running BootstrapTest (modified to use the CF
frontend).
