Added rudimentary C++0x attribute support.
...
The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
- align() - semantics believed to be conformant to n3000, except for
redeclarations and what entities it may apply to
- final - semantics believed to be conformant to CWG issue 817's proposed
wording, except for redeclarations
- noreturn - semantics believed to be conformant to n3000, except for
redeclarations
- carries_dependency - currently ignored (this is an optimization hint)

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between. Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?
// CHECK: 1
// CHECK: 2
// CHECK: 3
// CHECK: 4
// CHECK: 5
// CHECK: 6
would require 1 2 and 3 to be continuous in the output, and 4 5 and 6
to be continuous.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.
