OpenRISC cleanups and Fixes for QEMU 3.0

Mostly patches from Richard Henderson fixing multiple things:
* Fix singlestepping in GDB.
* Use more TB linking.
* Fixes to exit TB after updating SPRs to enable registering of state
changes.
* Significant optimizations and refactors to the TLB
* Split out disassembly from translation.
* Add qemu-or1k to qemu-binfmt-conf.sh.
* Implement signal handling for linux-user.

Then there are a few fixups from me:
* Fix delay slot detections to match hardware, this was masking a bug
in the linus kernel.
* Fix stores to the PIC mask register

target/openrisc: implement shadow registers

Shadow registers are part of the openrisc spec along with sr[cid], as
part of the fast context switching feature. When exceptions occur,
instead of having to save registers to the stack if enabled the CID will
increment and a new set of registers will be available.

This patch only implements shadow registers which can be used as extra
scratch registers via the mfspr and mtspr if required. This is
implemented in a way where it would be easy to add on the fast context
switching, currently cid is hardcoded to 0.

This is need for openrisc linux smp kernels to boot correctly.
