Sebastian bfbfeefbb3 reduce.py: Allow reducing error messages, print output in case of error (#2179)
* reduce.py: Allow reducing error messages, print output in case of error

Allow reducing code that triggers (false positive) error messages.
Print Cppcheck output in case Cppcheck returns unsuccessfully and no
segfault is expected. This helps fixing messed up command lines (for
example issues with the path).

* Use "else" as suggested

IOBYTE c32a568c1f fix #8965 ("(debug) Executable scope 'x' with unknown function." with rvalue parameter in method) (#2237)
I fixed the AST enough to pass testrunner but I don't believe it is
correct.

This code:

void Foo4(int&&b);

has this AST:

( 'void'
|-Foo4
`-&& 'bool'
  |-int
  `-b 'signed int'

but I don't believe && should have `bool`.
