[M3devel] record types in backend

[Jay K]

In debugging this..the gcc code wants to enumerate the fields of a struct.
We spend the effort building up most of this information, but we never hook it up to the parameter.
 The fields are null. From debugging it.

Then from reading our code:
declare_param:
  m3_build_type
    case T_struct:
      {
        tree ts = make_node (RECORD_TYPE);
        TYPE_FIELDS (ts) = NULL_TREE;

Seems to me we should have a hash of typeid to tree, and here we should look
up the typeid and set the fields appropriately.

I'll try that.

Besides fixing SPARC64_SOLARIS here, it should dramatically improve debugging with stock gdb.
We'll see.

It turns out 4.3.5 fails the same way.
