Add #pragma clang attribute

This is a recommit of r300539 that was reverted in r300543 due to test failures.
The original commit message is displayed below:

The new '#pragma clang attribute' directive can be used to apply attributes to
multiple declarations. An attribute must satisfy the following conditions to
be supported by the pragma:
- It must have a subject list that's defined in the TableGen file.
- It must be documented.
- It must not be late parsed.
- It must have a GNU/C++11 spelling.
