[patch] Fix PR c++/28053

["Lee Millward" <lee dot millward at codesourcery dot com>]

Hi,

The following testcase triggers a seg fault in the middle-end:

struct X {};

struct A
{
   X x : 2;
};

struct B : A {};

The attached fixes this by moving the diagnosis of non-integral
bitfields from check_bitfield_decl to grokbitfield, allowing the
invalid declaration to be discarded.

Bootstrapped and regression tested on i686-pc-linux-gnu, ok for mainline?

Cheers,
Lee.
