Richard Henderson 07f30382c0 cputlb: Handle watchpoints via TLB_WATCHPOINT 
The raising of exceptions from check_watchpoint, buried inside
of the I/O subsystem, is fundamentally broken. We do not have
the helper return address with which we can unwind guest state.

Replace PHYS_SECTION_WATCH and io_mem_watch with TLB_WATCHPOINT.
Move the call to cpu_check_watchpoint into the cputlb helpers
where we do have the helper return address.

This allows watchpoints on RAM to bypass the full i/o access path.

Backports commit 50b107c5d617eaf93301cef20221312e7a986701 from qemu
