target-xtensa: implement instruction breakpoints Add IBREAKA/IBREAKENABLE SRs and implement debug exception, BREAK and BREAK.N instructions and IBREAK breakpoints. IBREAK breakpoint address is considered constant for TB lifetime. On IBREAKA/IBREAKENABLE change corresponding TBs are invalidated. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
