Fix #9399 (Build Failure on x86: error: unknown type name '__int128_t') ( #2254 )
...
https://stackoverflow.com/questions/16088282/is-there-a-128-bit-integer-in-gcc
suggests to test for __SIZEOF_INT128__. This test is added now and
Cppcheck now also compiles for a 32 bit target with the expected
warning that there is no 128-bit integer. "make test" also works.

Parse `extern "C"`, and use it to avoid FP reference warnings ( #2234 )
...
Previously, cppcheck discarded the `extern "C"` specifier. This patch modifies cppcheck to parse each as a Scope in the symbol database, then uses that scope to avoid false positives when making recommendations about changing a function argument to be a reference (since variable references is a C++ feature, unavailable in C, and thus unavailable in `extern "C"`).

Fix #9299 (Makefile: tools/matchcompiler.py is executed via Python 2) ( #2247 )
...
Check if "python" is available, if not check for "python3" and use
the available Python interpreter. If no Python interpreter is found,
"make" fails with an according error message.
This solves the issue that not all modern Linux distributions any longer
install Python 2 by default, so "python" is not available and
"make MATCHCOMPILER=yes" would fail. Instead of forcing the users to
install Python 2, Python 3 is used in such a case now if it is
available.

Allow reducing code that triggers (false positive) error messages.
Print Cppcheck output in case Cppcheck returns unsuccessfully and no

example issues with the path).

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`.
