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"`).

This fixes crashes found by daca where valueType() is NULL. Also,
somewhat related, it removes warnings when casting to a type that is
unknown to cppcheck, for example, there is no longer a warning for the
following code:
void* f() {
void *x = malloc(1);
return (mytype)x;
}

Fix false negatives in checkAssignBoolToFloat and minor related improvements ( #2198 )
...
* Fix false negatives in checkAssignBoolToFloat
Detect assignments to expressions involving pointer dereferences, array
element accesses, etc.
* Pass assignment token to assignBoolToFloatError
Pass assignment token rather than boolean token to make error reporting
consistent between checkAssignBoolToFloat and checkAssignBoolToPointer,
as well as with other assignment checks in the code base.
* Make checkAssignBoolToPointer check consistent with checkAssignBoolToFloat

Fix #9343 (memleak FP when return with cast) ( #2162 )
...
This was most likely introduced when the checks were changed to run on
the full tokenlist instead of the simplified one.
Take care to warn about cases where casts destroy the pointer, such as
uint8_t f() {
void* x = malloc(1);
return (uint8_t)x;
}
