Maciej W. Rozycki 9dbca9e8a9 MIPS: Fix unaligned PC interpretation in `compute_return_epc' ...

commit 11a3799dbe upstream.

Fix a regression introduced with commit fb6883e580 ("MIPS: microMIPS:
Support handling of delay slots.") and defer to `__compute_return_epc'
if the ISA bit is set in EPC with non-MIPS16, non-microMIPS hardware,
which will then arrange for a SIGBUS due to an unaligned instruction
reference.  Returning EPC here is never correct as the API defines this
function's result to be either a negative error code on failure or one
of 0 and BRANCH_LIKELY_TAKEN on success.
