    testsuite, c, Darwin: Fix Mach-O issues in toplevel asm tests.
    
    Current Darwin no longer supports non-pie executables, leading to spurious
    fails because of linker warnings; skip these cases.
    
    Several of the tests also needed updates for Mach-O ABI (e.g asm directive
    spellings or USER_LABEL_PREFIX).  This fixes the UNRESOLVED cases but not
    the actual fail of toplevel-simple-asm-2.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/lto/toplevel-extended-asm-2_0.c: Fix Mach-O syntax.
            * gcc.dg/lto/toplevel-extended-asm-2_1.c: Likewise.
            * gcc.dg/lto/toplevel-simple-asm-2_1.c: Fix Mach-O syntax.
