c++: Diagnose bare parameter packs in bitfield widths [PR99745]

The following invalid tests ICE because we don't diagnose (and drop) bare
parameter packs in bitfield widths.

PR c++/99745
* decl2.c (grokbitfield): Diagnose bitfields containing bare parameter
packs and don't set DECL_BIT_FIELD_REPRESENTATIVE in that case.

* g++.dg/cpp0x/variadic181.C: New test.
