Assume the function pointers retrieved by alGetProcAddress are context
independent. This is not likely to change in any implementation we
care about any time soon.

This ensures there's no multilevel indirection in the state table.

dbghelp: When handling a P augmentation in FDE/DIE parsing, throw away the DW_EH_indirect flag, as we don't handle the result.

It's needed as long as we don't support DW_EH_indirect while reading encoded values.

Implement dwarf stack unwinding for i386 CPU.

We should never call the handler for states that have a rep.

This is not yet generalized to "pause all" or "stop all".
