target/m68k: implement m68k "any instruction" trace mode
The m68k trace mode is controlled by the top 2 bits in the SR register. Implement the m68k "any instruction" trace mode where bit T1=1 and bit T0=0 in which the CPU generates an EXCP_TRACE exception (vector 9 or offset 0x24) after executing each instruction. This functionality is used by the NetBSD kernel debugger to allow single-stepping on m68k architectures.
