    PR23800, .eqv doesn't always defer expression evaluation

    .eqv (and ==) ought not simplify expressions involving dot or other
    symbols set by .eqv.  If such simplification occurs, the value of dot
    will be that at the assignment rather than at the place where the
    symbol is used.

        PR 23800
        * expr.c (expr): Don't simplify expressions involving forward_ref
        symbols when mode is expr_defer.
        * config/tc-spu.c (spu_cons): Parse expression using normal
        expression evaluation if @ppu is not detected.
        * testsuite/gas/all/eqv-dot.d,
        * testsuite/gas/all/eqv-dot.s: New test.
        * testsuite/gas/all/gas.exp: Run it.
