    testsuite, rs6000: Remove powerpc_popcntb_ok
    
    There are three uses of effective target powerpc_popcntb_ok,
    they are all for compiling, but powerpc_popcntb_ok checks
    for executable generation, which is too heavy.  This patch
    is to remove powerpc_popcntb_ok and adjust its three uses
    accordingly.
    
    gcc/testsuite/ChangeLog:
    
            * lib/target-supports.exp 
(check_effective_target_powerpc_popcntb_ok):
            Remove.
            * gcc.target/powerpc/cmpb-2.c: Adjust with dg-skip-if as
            powerpc_popcntb_ok gets removed.
            * gcc.target/powerpc/cmpb-3.c: Likewise.
            * gcc.target/powerpc/cmpb32-2.c: Likewise.
