- 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.

This should reduce memory requirements in several cases and at the same
time fix a long standing correctness issue where we spilled float values
with 64bit precision instead of the full 80bit on x87.

- We now create a spill/reload/phi-web and take the largest necessary
  reload size to determine the size of the entities and the spills.
- Some cleanups

- collect_and_rewire_users failed for users in other blocks: we really
  needed an SSA reconstruction
- Needed to shuffle the stored value to TOS before storing it
