    Fix 'main' function in 'gcc.dg/builtin-dynamic-object-size-pr120780.c'
    
    Fix-up for commit 72e85d46472716e670cbe6e967109473b8d12d38
    "tree-optimization/120780: Support object size for containing objects".
    'size_t sz' is unused here, and GCC/nvptx doesn't accept this:
    
        spawn -ignore SIGHUP [...]/nvptx-none-run 
./builtin-dynamic-object-size-pr120780.exe
        error   : Prototype doesn't match for 'main' in 'input file 1 at offset 
1924', first defined in 'input file 1 at offset 1924'
        nvptx-run: cuLinkAddData failed: unknown error (CUDA_ERROR_UNKNOWN, 999)
        FAIL: gcc.dg/builtin-dynamic-object-size-pr120780.c execution test
    
            gcc/testsuite/
            * gcc.dg/builtin-dynamic-object-size-pr120780.c: Fix 'main' 
function.
    
    (cherry picked from commit c6ca6e57004653b787d2d6243fe5ee00cda8aad0)
