Compiling the following test with assertion-enabled clang results in the assertion failure.
https://github.com/gcc-mirror/gcc/blob/master/gcc/testsuite/gcc.dg/pr70022.c
Backtrace:
```console
clang: /root/llvm-project/llvm/include/llvm/ADT/APSInt.h:100: int64_t llvm::APSInt::getExtValue() const: Assertion `isRepresentableByInt64() && "Too many bits for int64_t"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
