Make == for associative arrays test for equality, not identity. _aaEq was added to runtime/internal/aaA.d which forwards to TypeInfo_AssociativeArray.equals in genobj.d. On the codegen side, DtoAAEquals was added to gen/aa.cpp and is called from EqualExp::toElem in gen/toir.cpp. I assume that the frontend will produce an error if == is used on associative arrays of different type. This fixes DMD bug 1429.

This is the source code to the front end Digital Mars D compiler.
It covers the lexical analysis, parsing, and semantic analysis
of the D Programming Language defined in the documents at
www.digitalmars.com/d/

The optimizer, code generator, and object file generator are not part
of this source, hence the source does not currently constitute a complete,
compilable program. However, many people have expressed a strong interested
in producing a D compiler with the GNU compiler sources. This release should
enable that.

These sources are free, they are redistributable and modifiable
under the terms of the GNU General Public License (attached as gpl.txt),
or the Artistic License (attached as artistic.txt).

It does not apply to anything else distributed by Digital Mars,
including D compiler executables.
