llvm-gcc4.0 support dropped - please update testers

LLVMers,

LLVM 2.2 will be the final release that llvm-gcc4.0 is supported. Support has already been dropped in mainline (ie. patches to llvm-gcc4.2 are no longer being back ported).

For those running a nightly tester, please upgrade to llvm-gcc4.2.

If you have questions, please direct responses to the list.

Thanks,
Tanya Lattner
