- add ps.callinc to the TB flags, that allows testing all instructions
for window overflow statically;
- drop gen_window_check* functions; replace them with get_window_check
that accepts bitmask of used registers;
- add XtensaOpcodeOps::test_overflow that returns bitmask of implicitly
used registers; use it for entry and call{,x}{4,8,12};
- drop window overflow test from the entry helper;
- drop parameter 0 from translate_[di]cache and use translate_nop for
d/i cache opcodes that don't need memory accessibility check;
- add bitmask XtensaOpcodeOps::windowed_register_op that marks opcode
arguments that refer to windowed registers;
- translate windowed_register_op mask to a mask of actually used
registers in the disassembly loop;
- add check for window overflow right after the check for debug
exception;
