[PATCH][AArch64/arm] PR testsuite/85326 Avoid C++ tests when C++ compiler not present

[Kyrill Tkachov <kyrylo dot tkachov at foss dot arm dot com>]

Hi all,

This patch makes the arm and aarch64 testsuite safe for when a C++ compiler is not present.
This involves moving .C files into g++.dg/other/ and guarding them with the appropriate target check.

For others it just means renaming them from .C to .c.

For gcc.target/aarch64/simd/pr67896.C this means adjusting the error messages to look
for the errors that the C frontend gives for conflicting types rather than what C++ gives.

This fixes the errors seen when testing a non-bootstrapped C-only GCC and the tests
still pass on normal testing setups and the tests that are in g++.dg appear UNSUPPORTED
on the targets that they don't pertain to.

Tested this on arm-none-linux-gnueabihf and aarch64-none-linux-gnu.

Ok for trunk?

Thanks,
Kyrill
