Re: PR11867, bignum operations

I'm going to remove it.  A quad value will fit in a 64-bit bfd_vma.
Testing bignum operations effectively requires .octa, as in the
following patch.  I'll commit it when testing completes.

	* gas/all/octa.s, * gas/all/octa.d: New test.
	* gas/all/gas.exp: Run octa.
	* gas/elf/data-1.s, * gas/elf/data-1.d: Delete.
	* gas/elf/elf.exp: Don't run data-1.
