fix: promote mismatched comparison operands before emitting cmp (issue 0146)

Browse Source 
A comparison with int-vs-float (or two float widths) operands emitted cmp on
the raw operands with no promotion, unlike the arithmetic arms -- producing a
mixed-type compare the LLVM verifier rejects / mis-evaluates. lowerBinaryOp now
coerces each operand to the promoted common type (from arithResultType) via
coerceToType (SIToFP / FPExt) for the ordering/equality arms when the promoted
type is a float, so LLVM gets a well-typed fcmp.
