[vm/inliner] Inline small int convertors.

Rationale:
Always inline int convertors that don't do
much more than testing and anding.
For example, force inline
  v26 <- StaticCall:66( _toUint8@6027147<0> v4 T{Type: class 'int'?}) T{Type: class 'int'?}
to
  v47 <- Constant(#255)
  ..
  CheckSmi:10(v4 T{Type: class 'int'?})
  v45 <- BinarySmiOp:10(&, v4 T{_Smi}, v47 T{_Smi}) T{_Smi}
