target/microblaze: Convert brk and brki to decodetree
Split these out of the normal branch instructions, as they require
special handling. Perform the entire operation inline, instead of
raising EXCP_BREAK to do the work in mb_cpu_do_interrupt.
This fixes a bug in that brki rd, imm, for imm != 0x18 is not
supposed to set MSR_BIP. This fixes a bug in that imm == 0 is
the reset vector and 0x18 is the debug vector, and neither should
raise a tcg exception in system mode.
Introduce EXCP_SYSCALL for microblaze-linux-user.
