[PATCH] Preserve paramater attributes during template instantiation

[Jordan Rose]

  Use a FunctionProtoType::ExtProtoInfo in Sema::BuildFunctionType if one is available.

  I'm not sure we actually need to keep the old overload of BuildFunctionType around; there aren't any callers anymore. What do you think? Should we just require ExtProtoInfo all the time?

  Also, drop attributes in StripImplicitInstantiation (though since `ns_consumed` and friends are type-sensitive, it will refuse an explicit specialization without them anyway).

  This patch depends on ArrayRef-ization of Sema::BuildFunctionType and ASTContext::getFunctionType, which I'm about to commit once it passes all the tests.
