Pietro Fezzardi 6acd265c5a Add revng helpers to decompile llvm::UndefValue ...

Before this commit, we used to decomple UndefValue to the literal 0.

This was causing problems in some cases, such as switch(0 /*undef*/)
where clang was issuing a warning that was impossible do disable without
turning off -Wall alltogether, which is undesirable.

This commit introduces a set of helper functions in
revng-primitive-types.h, that are now used to avoid emitting undef as
constant.
This is more semantically meaningful when looking at the decompiled
code, and it has the nice side effect that it silences the clang
warnings mentioned above.
