Partial fix for PR7267 based on comments by John McCall on an earlier patch.
This is more targeted, as it simply provides toggle actions for the parser to
turn access checking on and off. We then use these to suppress access checking
only while we parse the template-id (included scope specifier) of an explicit
instantiation and explicit specialization of a class template. The
specialization behavior is an extension, as it seems likely a defect that the
standard did not exempt them as it does explicit instantiations.

This allows the very common practice of specializing trait classes to work for
private, internal types. This doesn't address instantiating or specializing
function templates, although those apparently already partially work.

The naming and style for the Action layer isn't my favorite, comments and
suggestions would be appreciated there.

now get dce'd by the inliner.  Hence all the changes to
builtins-ppc-altivec.c to ensure the calls aren't dead.

Chandler Carruth [Fri, 25 Jun 2010 03:22:07 +0000 (03:22 +0000)]
Implement dependent alignment attribute support. This is a bit gross given the
current attribute system, but it is enough to handle class templates which
specify parts of their alignment in terms of their template parameters.

This also replaces the attributes test in SemaTemplate with one that actually
tests working attributes instead of broken ones. I plan to add more tests here
for non-dependent attributes in a subsequent patch.

Thanks to John for walking me through some of this. =D
