PR c++/53540 - using fails to be equivalent to typedef
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.

PR middle-end/54860 - Make sure attributes hash table is created
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.

PR c++/53528 C++11 attribute support
This patch implements the c++-11 generalized attributes, described in
the N2761 paper[1].
The idea is to modify the front-end to accept the new attribute syntax
(including alignas expressions) and to build an internal
representation similar to the one we already have for GNU attributes.
This lets us re-use our existing GNU attribute mechanisms to support
the generalized c++11 attributes.
The patch does change the existing internal representation to support
scoped attribute (aka attributes with namespaces), which is a concept
that doesn't exist in GNU attributes. I have thus put all existing
GNU extension attributes into the "gnu" namespace. For instance, in
C++-11, the "unused" attribute would be represented as
"[[gnu::unused]]". Because there is no syntax for scoped attributes
in C, writting "__attribute__((unused))" unconditionnally refers to
the "unused" attribute in the "gnu" namespace.
Note that this patch follows a conservative understanding of the
specification by disallowing attributes appertaining to types, unless
they apply to a type definition.

(TARGET_EXPAND_TO_RTL_HOOK): Define.
* config/mips/mips.md (move_type): Add imul.
(type): Map imul move_types to imul.
(*movdi_32bit, *movti): Add imul alternatives.
Use mips_split_move_insn_p and mips_split_move_insn instead of
mips_split_64bit_move_p and mips_split_doubleword_move in move
splitters.
