The jFirm generator reuses the code in spec_util and needs these
defaults too.

- Compound type selection is performed with Member
- Array indexing is performed with Sel
- Instead of the simpleSel constructor functions you can use the normal Member
  constructors now
- The concept of array element entities has been removed, Sel nodes just
  contain a pointer to the array type now.

- is_address_taken() according to its own logic was only valid when
  called with a Sel node
- Tuples where skipped although irg_properties ensured no tuples in the
  graph anyway.
- Call and default case could be merged.
- Id case would have failed if taken (is_address_taken called with Id
  instead of Sel)

We still have the vc2010 files in here

By default a node needs the graph explicitly given iff it has a known block.

Just inspecting the attribute block is sufficient.

- Always print mode for Bad and Proj
- Do not print mode M and X

Also remove useless pointer to int casts.

This should fix 400.perlbench which was using a 16bit stackent here.

We have a bad situation here as at the time of reload folding we can't
predict yet whether the spillslot coalescer must enlarge the spillslot
to 80bit precision.
For now I fix it by not folding reloads into x87 nodes. The better
alternative which I didn't do yet are:
- Move the spillslot coalescing to an earlier place before reload
  folding. This is somewhat tricky as the reload folding is implemented
  in generic code, while coalescing is backend specific.
- Revert folded AM when the spillslot is widened.

The new spillslot coalescing sometimes produces 2byte memperms which the
old code couldn't handle.
