The output of "-cpu help" is currently rather confusing to the users:
It might not be fully clear which part of the output defines the CPU
names since the CPU names contain white spaces (which we later have to
convert into dashes internally). At best it's at least a nuisance since
the users might need to specify the CPU names with quoting on the command
line if they are not aware of the fact that the CPU names could be written
with dashes instead. So let's finally clean up this mess by using dashes
instead of white spaces for the CPU names, like we're doing it internally
later (and like we're doing it in most other targets of QEMU).
Note that it is still possible to pass the CPU names with spaces to the
"-cpu" option, since sparc_cpu_type_name() still translates those to "-".

Commit b447378e12 ("qom/object: Limit type names to alphanumerical ...")
cut down the amount of allowed characters for QOM types to a saner set.
The "+" character was meant to be included in this set, so we had to
add a hack there to still allow the legacy names of POWER and Sparc64
CPUs. However, instead of putting such a hack in the common QOM code,
there is a much better place to do this: The sparc_cpu_class_by_name()
function which is used to look up the names of all Sparc CPUs.
Thus let's finally get rid of the "+" in the Sparc CPU names, and provide
backward compatibility for the old names via some simple checks in the
sparc_cpu_class_by_name() function.

We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

In order to ease static analysis when running

replace:
- CPU_GET_CLASS(cpu);
+ CPU_GET_CLASS(obj);
Most code use the 'cs' variable name for CPUState handle.

If an exception is to be raised, the destination fp register
should be unmodified. The current implementation is incorrect,
in that double results will be written back before calling
gen_helper_check_ieee_exceptions, despite the placement of
gen_store_fpr_D, since gen_dest_fpr_D returns cpu_fpr[].
We can simplify the entire implementation by having each
FPOp helper call check_ieee_exceptions. For the moment this
requires that all FPop helpers write to the TCG global cpu_fsr,
so remove TCG_CALL_NO_WG from the DEF_HELPER_FLAGS_*.
