release notes: please mention Intrinsic::memory_barrier removal in 3.0

Hi,

Looks like the memory_barrier intrinsic got removed in 3.0 and replaced with fence intrinsics.
Could someone who understands this change better than me please update the 3.0 release notes?
Also the LangRef still mentions llvm.memory.barrier but this is gone from 3.0.

Best regards,

r142994 and r142998 for the relevant changes.

Any comments on your transition would be appreciated.

Thanks.
My code compiles now, but I haven't actually had time to test it on a non-x86 architecture
(on an x86 architecture the fence I was using was a nop).
I'll probably do some tests in the weekend and let you know how the conversion went.

Best regards,
--Edwin

Do these need to go into the 3.0 branch?

r142994 is necessary; I thought I already sent you an email about
that. r142998 only touches the release notes; it looks like you're
hacking on those on trunk.

Dunno if I got it. It's in now. Thanks!
