In commit 1bba0dc932 cpu_reset()
was renamed to cpu_state_reset(), to allow introducing a new cpu_reset()
that would operate on QOM objects.
All callers have been updated except for one in target-mips, so drop all
implementations except for the one in target-mips and move the
declaration there until MIPSCPU reset can be fully QOM'ified.

ocbp and ocbwb controls the writeback of a cache line to memory. They
are supposed to do nothing in case of a cache miss. Given QEMU only
partially emulate caches, it is safe to ignore these instructions.

Function gen_pc_load was introduced in commit
d2856f1ad4.
The only reason for parameter searched_pc was
a debug statement in target-i386/translate.c.
Parameter puc was needed by target-sparc until
commit d7da2a1040.
Remove searched_pc from the debug statement and remove both
parameters from the parameter list of gen_pc_load.
As the function name gen_pc_load was also misleading,
it is now called restore_state_to_opc. This new name
was suggested by Peter Maydell, thanks.
v2: Remove last parameter, too, and rename the function.
v3: Fix [] typo in target-arm/translate.c.

All implementations are now the same, and there is only one caller,
so inline the function there.

All targets except SH4 have the same cpu_halted() routine, and it has
only one caller. It is therefore a good candidate for inlining.
The difference is the handling of the intr_at_halt, which is necessary
to ignore SR.BL when sleeping. Move intr_at_halt handling out of it, by
setting this variable while executing the sleep instruction, and
clearing it when the CPU has been woken-up by an interrupt, whatever the
state of SR.BL. Also rename this variable in_sleep.
