target-xtensa: add ICOUNT SR and debug exception
ICOUNT SR gets incremented on every instruction completion provided that
CINTLEVEL at the beginning of the instruction execution is lower than
ICOUNTLEVEL.
When ICOUNT would increment to 0 a debug exception is raised if
CINTLEVEL is lower than DEBUGLEVEL.
See ISA, 4.7.7.5 for more details.
