The new design simply lets you specify hex or not in tarval_snprintf.
This is way simpler than the previous machinery and enough for all users in
libfirm.

The API is not really used, has nothing to do with compilers and uses
glibc/linux/windows specific extensions.

Assembler/linker never supported this anyway.

This fixes a crash bug in C/cp_error077.c

When killing the CopyB we have to use the CopyBs memory input instead of
the Call memory input. To do this I had to rework/improve a previous hack/fix
for const calls with compound return.

This allows the fronted to register a dump+verify callback for the
lowering transformations performed by the backends.

- Only allow get_entity_irg()/set_entity_irg() for method entities now.
- Allow setting/getting of additional properties for method and alias
  entities.
- Add some missing is_method_entity() checks in cgana.

Most firm analyses behaved incorrectlye when: A called SymConst did not
have a method entity, assumed the code reachable by get_entity_irg is
the code called. These assumptions are wrong when doing crazy casts in C
or when dealing with weak symbols. This is fixed by introducing some
convenience functions: get_Call_callee(), get_entity_linktime_irg()

This fixes a bug where the code path handling immediate evaluation was
not able to evaluate some Cmp(Confirm, Const) combinations, but the
normal code could do it.

(This also fixes occult3.c as calling localopts changed the graph in
 this case with the conv phase still confirming all irg properties)

This also fixes issues where the no_critical_edges flag was not cleared.

We first have to create the new replacement store after the phi, so the
following removal of the old nodes does not assume the ptr input value is
unused and kills it.

All users of NEW_ARR_A used it to construct a simple array, yet noone
cared about it actually being an array with a length field in front. For
this simple use case you should use ALLOCAN.
