[PATCH] Testsuite: Mark check_effective_target_exceptions_enabled test as C++ test input.

[Tamar Christina]

Hi All,

The test in check_effective_target_exceptions_enabled uses a C++ keyword `throw`
and the test fails with a syntax error on any non-g++ test.  I now tell the
testsuite driver that this is a C++ input file so it runs it as such in all the
drivers.

Regtested on aarch64-none-linux-gnu and no issues.

Ok for master?

Thanks,
Tamar
