    ipa/100513 - fix SSA_NAME_DEF_STMT corruption in IPA param manip

    This fixes unintended clobbering of SSA_NAME_DEF_STMT of the
    cloned/inlined from SSA name during IPA parameter manipulation
    of call stmt LHSs.  gimple_call_set_lhs adjusts SSA_NAME_DEF_STMT
    of the lhs to the stmt being modified but when
    ipa_param_body_adjustments::modify_call_stmt is called the
    cloning/inlining process has not yet remapped the stmts operands
    to the copy variants but they are still original.

            altering SSA_NAME_DEF_STMT by adjusting the calls LHS
            via gimple_call_lhs_ptr.
