c++: Fix decltype-bitfield1.C on i?86

Browse Source 
This test was failing on i?86 because of:

warning: width of 'A::l' exceeds its type

so change the type to 'long long' and make the test run only on arches
where sizeof(long long) == 8 to avoid failing like this again.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/decltype-bitfield1.C: Change a type to unsigned
	long long.  Only run on longlong64 targets.
