Rework type & size inference, literal usage
Fixes a bug in the old type inference mechanism (wasn't properly
propogating type info across Phi & move nodes). Combined type and
size inferences passes.
Fixed long-standing bug in the code to load a special double-precision
immediate (would have been extremely difficult to hit this in the field).
Improved loading floating point immediates.
