Sebastian b7e48a9b27
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.
