JVM IR: fix operand type for CompareTo intrinsic

Browse Source 
It's incorrect to take the first parameter type from the expression
itself because it can be nullable if smart casts are used. And if it's
nullable, it's mapped to the wrapper type and calling
`comparisonOperandType` for it makes no sense. Instead, take the type
from the callee function, as it's guaranteed to be mapped to a JVM
primitive type.

E.g. in `test1` function in the added test, the problem was that the
dispatch receiver type of the call expression is `Double?`, which is
mapped to `java/lang/Double`, whereas we clearly wanted to obtain the
primitive `D` (double) type.
