    rs6000, add overloaded DFP quantize support

    Add decimal floating point (DFP) quantize built-ins for both 64-bit DFP
    and 128-DFP operands.  In each case, there is an immediate version and a
    variable version of the built-in.  The RM value is a 2-bit constant int
    which specifies the rounding mode to use.  For the immediate versions of
    the built-in, the TE field is a 5-bit constant that specifies the value of
    the ideal exponent for the result.  The built-in specifications are:

      __Decimal64 builtin_dfp_quantize (_Decimal64, _Decimal64,
                                        const int RM)
      __Decimal64 builtin_dfp_quantize (const int TE, _Decimal64,
                                        const int RM)
      __Decimal128 builtin_dfp_quantize (_Decimal128, _Decimal128,
                                         const int RM)
      __Decimal128 builtin_dfp_quantize (const int TE, _Decimal128,
                                         const int RM)

    A testcase is added for the new built-in definitions.

    gcc/ChangeLog:
            * config/rs6000/dfp.md (UNSPEC_DQUAN): New unspec.
            (dfp_dqua_<mode>, dfp_dquai_<mode>): New define_insn.
            * config/rs6000/rs6000-builtins.def (__builtin_dfp_dqua,
            __builtin_dfp_dquai, __builtin_dfp_dquaq, __builtin_dfp_dquaqi):
            New buit-in definitions.
            * config/rs6000/rs6000-overload.def (__builtin_dfp_quantize): New
            overloaded definition.
            * doc/extend.texi: Add documentation for __builtin_dfp_quantize.

    gcc/testsuite/
            * gcc.target/powerpc/pr93448.c: New test case.
