[ C++ 4.6 Patch] allow uninitialized const or reference members with -fpermissive

[Fabien Chêne]

Hi,

As discussed off-list with Jason, it would be better to use permerror
instead of error when diagnosing uninitialized const or reference
members. At least for 4.6.
That would be usefull to provide a transition for invalid code that
exploits the following accept-invalids: PR 25811, PR 43719, PR 44086.
I have changed error to permerror only for the cases where it was
needed for the PR listed above.

OK for the 4.6 branch ?
