    rs6000: clean up headers in rs6000.c and rs6000-call.c
    
    When Andrew Macleod investigated the recent rs6000 bootstrap failure,
    he suggested a clean up of the headers in rs6000.c and rs6000-call.c.
    It now is recommended to include ssa.h instead of the individual headers.
    This also ensures that value-range.h is included and in the correct order
    so that the tree-ssa-propagate.h inclusion of value-query.h and its
    dependencies are satisfied.
    
    Bootstrapped on powerpc-ibm-aix7.2.0.0 and powerpc64le-linux.
