The operands were swapped.

It was only used in an assertion.

The variable was initialised to this just a few lines above.

* It was retrieved from the arch_env before.
* Also rename be_abi_fix_stack_nodes() to be_fix_stack_nodes().

be: Remove the unused thin wrapper macros arch_register_class_index() and arch_register_class_name().

All other structs holding a register class call it cls, too.

ia32: Remove redundant calls to clear_ia32_use_frame()/set_ia32_use_frame() just after/before set_ia32_frame_ent().

It was just done before a few lines above.

ia32: Directly put the bitfields in ia32_attr_t instead of having another struct needlessly wrapping them.

This fixes opt/fehler270.c.

This fixes opt/fehler277.c.

This fixes opt/fehler269.c.

This way we do not need to create a new Proj, when we replace a Store + IncSP by a Push.

This avoids ProjMs for the wrong slot when a Load + IncSP is replaced by a Pop.

It was harmless here, because all Pop instructions use the same output slots here.
