Add be_dep_on_frame() to let a node depend on the frame, so it does not get scheduled before it can be spilled.

[r22625]

Remove unnecessary dependency edge from the IncSP, which destroys the stack frame, to the final memory Proj.  Most probably it is unnecessary since Projs are not scheduled anymore.

Do not mark the node as visited before transforming it.  This is not necessary anymore since Phis put their predecessors in a worklist, so we cannot walk in a circle.

[r22613]

[r22612]

Remove redundant be_set_transformed_node() in transformer functions.  They are vestiges of old transform semantics.  Their caller (transform helper) handles this.

  This happens for instance with AddP(x, NULL) and x.
  Add a Conv than.

Do not emit cld in the CopyB prologue.  The ABI mandates that DF is cleared, so do not bother performing this NOP.

Use separate code to emit suffixes for integer and floating point instructions, because GAS wants different suffixes for 16bit /integer/ operands ("w" vs. "s") for them.
