[AArch64] Fix build for non-default languages
The SVE PCS support broke go, D and Ada because those languages don't
call TARGET_INIT_BUILTINS. We therefore ended up trying to get the
TYPE_MAIN_VARIANT of a null __SVBool_t.
We shouldn't really need to apply TYPE_MAIN_VARIANT there anyway,
since the ABI-defined types are (and need to be) their own main
variants. This patch asserts for that instead.
