c++: Fix ICE on invalid alignas in a template [PR93530]
This fixes an ICE taking place in cp_default_conversion because we got
a SCOPE_REF that doesn't have a type and so checking
INTEGRAL_OR_UNSCOPED_ENUMERATION_TYPE_P (TREE_TYPE (exp)) will crash.
This happens since the recent Joseph's change in decl_attributes whereby
we don't skip C++11 attributes on types.
[dcl.align] is clear that alignas applied to a function is ill-formed.
That should be fixed, and we have PR90847 for that. But I think a more
appropriate fix at this stage would be the following: in a template we
want to splice dependent attributes and save them for later, and by
doing so avoid this crash.
PR c++/93530 - ICE on invalid alignas in a template.
* decl.c (grokdeclarator): Call cplus_decl_attributes instead of
decl_attributes.
* g++.dg/cpp0x/alignas18.C: New test.
