[Patch, testsuite, ObjC++] Add TLS tests.

[IainS <developer at sandoe-acoustics dot co dot uk>]

ObjC++ currently has no checks for TLS.

This patch follows the logic that ObjC++ is defined to be a superset  
of C++ and thus ObjC+ should pass the same set of tests as C++ (with  
specific additions for cases where tls is embedded within the ObjC++  
syntax).

The patch adds syntax checks in obj-c++.dg/tls and a smaller number of  
compile checks in dg-torture/tls

tested on {powerpc,i686}-apple-darwin9 and i686-pc-linux-gnu.

At present, there are two failing [torture] tests on linux when lto is  
enabled (these are most likely indicative of a general failure of lto  
with ObjC/C++).
