LOG: [clang][bytecode] Don't use throw as invalid in c++26 (#181150)

Don't pass a combination of `-std=c++26` and `-fcxx-exceptions` to tests
and then try to use `throw` as an invalid statement. C++26 actually has
working exceptions at compile time, even if that is currently not
implemented.

Removed:
