3847c54f3f Add NSConstantString implementation for v2 ABI. 
This is largely the version from the newabi branch, but with a few
cleanups made possible by other bug fixes in the GSString
implementations.

5a72e1cfa8 * Source/GSString.m: Remove GSString copyWithZone:. 
* Source/NSString.m: Raise exception when no is provided for the
string. This brings our implementation closer to the Cocoa one.
* Source/GSString.m: Add similar exceptions.

970c8cbd05 Revert "Fix memory corruption in NSException." 
Accidentally included unrelated changes.

This reverts commit 3b1e94ec5d.

3b1e94ec5d Fix memory corruption in NSException. 
If compiling without backtrace or BFD support, we initialise the
location to store return addresses incorrectly, leaving a dangling
pointer which we then right over.

Most consumers never read this, so it seemed to work most of the time by
just overwriting a random bit of memory.

This probably has security implications, because throwing an exception
can clobber random bits of memory, though not with attacker-controlled
data.

0ebb50f984 Fix logic error in GSPrivateRangeOfString. 
We were checking if the receiver was a specific class, then directly
accessing an ivar of target.  We were then checking if target is a
specific class and, if so, accessing the ivar or target.

This mostly worked because most GNUstep strings have the same
underlying implementation and so the check was passing and by
coincidence giving the correct value.  This breaks when GSTinyStrings
are used more often and was picked up by teaching the compiler to
generate GSTinyStrings for small string literals.

17d379a59a Optimise appending UTF-16 strings for formatting 
If the string being appended to already uses unichar as the underlying 
character type, append the new characters using memcpy() instead of
looping over them individually. Also includes test cases to verify that
nothing breaks.
