PR c++/54466 - ICE with alias template which type-id is const qualified
Consider this short example:
templatetypename T
struct X { };
templatetypename T
using Y = const XT;
using Z = Yint;
G++ crashes in lookup_class_template_1 while trying to build the alias
template instantiation Yint.
I think this is indirectly due to the fact that that
lookup_class_template_1 can now yield a const qualified type like
'const XT'.
As a consequence, the code in lookup_template_class_1 that was trying
to access the TYPE_STUB_DECL field of the result of
lookup_template_class_1 should now be adjusted to access the
TYPE_STUB_DECL of the main variant of the resulting type instead (and
that is TYPE_MAIN_DECL); because qualified types (constructed with
build_qualified_type) have their TYPE_STUB_DECL set to NULL.
Fixed thus and tested on x86_64-unknown-linux-gnu against trunk.

* pt.c (lookup_template_class_1): TYPE_STUB_DECL should be
accessed on the main variant of the type.

* g++.dg/cpp0x/alias-decl-26.C: New test file.
In the example of this patch, g++ crashes when trying to build the
alias template Yint

The second alias doesn't even have to be a template to show the problem:
templatetypename T
struct X { };
templatetypename T
using Y = const XT;
using Z = Yint;
