Thomas Preud'homme 1e8636f15a [FileCheck] Introduce substitution subclasses
Summary:
With now a clear distinction between string and numeric substitutions,
this patch introduces separate classes to represent them with a parent
class implementing the common interface. Diagnostics in
printSubstitutions() are also adapted to not require knowing which
substitution is being looked at since it does not hinder clarity and
makes the implementation simpler.
