- revert to always inline forced functions for now

 - put call entries into a double linked list, so we can remove them in any order
 - correctly handle recursive calls: use the new (copied) callee_env
 - correctly handle weights for self-recursive calls: due to inlining recursive calls might get promoted to self-recursive calls
 - maxsize is a hard limit now: even forced functions are not inlined anymore (otherwise it would be possible to "force" a recursive one)
 - forced inlines are handled like function with BIG benefice and inlined first (sorted by loop depth)
 - fixed some comments, simplified code

free_methods was a bad base for callgraph walks, use methods which have no callers (in the current compilation unit)

purposes, call it only if a node is really replaced.

  optimize graphs that might still be inlined because the meta-information is invalided then,
  do that as an additional step

- links NoMem by hand

 - check the argument and the parameter types for compatibility
 - can inline methods with "mostly" compatible call/entity types
 - better check for additional parameters

[r19867]

[r19859]

 - inline recursive calls in rary cases only (BIG benefice or all
   arguments constant)
 - change some weights to hopefully better values

- inline_method() invalidates analysis info, no need to do this again
