    middle-end/111253 - partly revert r11-6508-gabb1b6058c09a7

    The following keeps dumping SSA def stmt RHS during diagnostic
    reporting only for gimple_assign_single_p defs which means
    memory loads.  This avoids diagnostics containing PHI nodes
    like

      warning: 'realloc' called on pointer '*_42 = PHI <lcs.14_40(29),
lcs.19_48(30)>.t_mem_caches' with nonzero offset 40

    instead getting back the previous behavior:

      warning: 'realloc' called on pointer '*<unknown>.t_mem_caches' with
nonzero offset 40

            * c-pretty-print.cc (c_pretty_printer::primary_expression):
            Only dump gimple_assign_single_p SSA def RHS.
