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"`).

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`.
