    testsuite; Fix unprotected-allocas-1.c at -O3 [PR121684]
    
    The problem here is after  r16-101, the 2 functions containing alloca/VLA
    start to be cloned and then we un-VLA happens in using_vararray so this
    is no longer testing what it should be testing.
    The obvious fix is to mark using_vararray and using_alloca as noclone too.
    
    Pushed as obvious after a quick test to make sure it is now working.
