    Darwin, PPC, testsuite, backport fix for pr71785.
    
    Firstly, we adjust the test conditions to use non-PIC code for Darwin.
    Secondly, we have to account for out-of-line GPR restores which gives
    a false positive on one of the scan-assembler-not. Lastly, we make the
    test a bit more specific for Darwin - that it looks for absence of
    branches to local labels.

    	Backport from mainline.

    	* gcc.target/powerpc/pr71785.c: For Darwin, make test non-PIC,
    	expect the out-of-line GPR restore, and test specifically for
    	absence of branches to local labels.
