In the example of this problem report, during the substituting of int
into 'function', tsubst_aggr_type fails for the alias ctxt1. This is
because TYPE_TEMPLATE_INFO looks for the TEMPLATE_INFO of the ctxt1
alias at the wrong place and was wrongly finding it to be NULL.
Namely, it was looking for it in the DECL_TEMPLATE_INFO of the
declaration of the type -- as if ctxt1 was an alias template
specialization -- rather than looking for it in its
CLASSTYPE_TEMPLATE_INFO.
Fixed thus. The other hunks of the patch are a cleanup to make a
better use of alias_template_specialization_p.
Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

On targets cris-elf, alpha and sparc (for instance) it can happen that
the attribute_tables variable is empty for fortran. Thus
register_scoped_attributes (called by init_attributes) won't call
register_scoped_attributes, so the hash table member of
scoped_attributes is not created.
Later when we try to e.g, lookup an attribute by calling
lookup_scoped_attribute_spec, that NULL member hash table comes to
byte us as htab_find_with_hash crashes.
This patch fixes this by ensuring in register_scoped_attributes that
the hash table is created.
Tested on cris-elf, x86_64-unknown-linux-gnu against trunk and some
commenters on the bug bootstrapped it on alpha and sparc.

The current implementation of C++11 attributes forbids them from being
applied to a type unless the type is being declared. I forgot to
adjust g++.dg/cpp0x/gen-attrs-{8,36,37}.C that was being run only on
ia32.
Fixed thus, tested on i386-unknown-linux-gnu and
x86_64-unknown-linux-gnu against trunk.

A couple of obj-c++ tests were failing[1] because the tokens '[[' can
either be the beginning of a c++11 attribute (that is itself at the
beginning of a statement), or the beginning of a nested
objc-message-expression. This patch resolves the ambiguity by
tentatively parsing the c++11 attribute and if it fails, then consider
the objc-message-expression.
I missed this initially because it didn't occur to me that
--enable-languages=all,ada does not include obj-c++. Shame on me. I
have now updated my compile farm scripts to use
--enable-language=all,ada,obj-c++,go and I
