cb5bbd2197 [CPP-340] When warning about mismatched parameters, follow what C 
compilers do.  Various integral and floating-point types
          are treated as mutually implicitly convertible.  Remaining
          warnings deal with misuse of pointer and array types.

10585e719d C++: Support widening casts in range analysis 
This makes sure we can conclude from `(int)myShort == 0` that `myShort`
is 0 even though we can no longer conclude from `(short)myInt == 0` that
`myInt` is 0. Without this, we lost a good result in the test for
`InfiniteLoopWithUnsatisfiableExitCondition.ql`.

669ac2f4b4 C++: Fix FP in PointlessComparison due to preprocessor 
Reported by an LGTM customer here: https://discuss.lgtm.com/t/2-false-positives-in-c-for-comparison-is-always-same/1943.

Even though the comparison is pointless in the preprocessor configuration in effect during extraction, it is not pointless in other preprocessor configurations. Similar to ExprHasNoEffect, we'll now exclude results in functions that contain preprocessor-excluded code. I factored the similar code already used in ExprHasNoEffect in a non-recursive version into Preprocessor.qll, leaving the recursive version in ExprHasNoEffect.ql. I believe the recursive version is too aggressive for PointerlessComparison, which does no interprocedural analysis.
