jit.exp: support C++ testcases
gcc/jit/ChangeLog: * TODO.rst (Test suite): Remove item about running C++ testcases. * docs/internals/index.rst (Working on the JIT library): Add "c++" to the enabled languages in the suggested "configure" invocation, and add a description of why this is necessary. * docs/_build/texinfo/libgccjit.texi: Regenerate. gcc/testsuite/ChangeLog: * jit.dg/jit.exp: Load wrapper.exp with %{tool} set to "g++" rather than "jit". Load g++.exp, and call g++_init. Run test-*.cc files within the testsuite and *.cc files within docs/examples. (jit-dg-test): Drop the addition of -fgnu89-inline to DEFAULT_CFLAGS in favor of adding it to additional_flags, only doing it when compiling C testcases (since g++ does not handle it). Reset "orig_environment_saved" so that LD_LIBRARY_PATH is restored to the value after g++_init ran, rather than the value before g++_init ran. Return a list of $comp_output $output_file, as dg-test assumes. From-SVN: r219318
