Max Filippov f29cf77609 xtensa: add load/store exception handler
Memory attached to instruction bus of the xtensa CPU is only accessible
for a limited subset of opcodes. Other opcodes generate an exception
with the load/store error cause code. This property complicates use of
such systems. Provide a handler that recognizes and transparently fixes
such exceptions. The following opcodes are recognized when used outside
of FLIX bundles: l32i, l32i.n, l16ui, l16si, l8ui.
