qom/object: Don't poll cast cache for NULL objects

object_dynamic_cast_assert used to be tolerant of NULL objects and not
assert. It's clear from the implementation that this is the expected
behavior.

The preceding check of the cast cache dereferences obj however causing...

qom: aggressively optimize qom casting

This patch adds a small typename cache to ObjectClass. This allows
caching positive casts within each ObjectClass. Benchmarking a
PPC workload provided by Aurelien, this patch eliminates every
single g_hash_table_lookup() happening during the benchmark (which...

qom: add a fast path to object_class_dynamic_cast

For leaf classes, in many cases the callbacks will simply downcast
the object back to the original class. Add this fast path to
object_class_dynamic_cast, object_dynamic_cast will inherit it.

qom: trace asserting casts

This provides a way to detect the cast that leads to a (reproducible)
crash even when QOM cast debugging is disabled.

qom: allow turning cast debugging off

Cast debugging can have a substantial cost (20% or more). Instead of adding
special-cased "fast casts" in the hot paths, we can just disable it in
releases. The tracing facilities we just added make it easier to analyze...

cpu: Move cpu_write_elfXX_note() functions to CPUState

Convert cpu_write_elfXX_note() functions to CPUClass methods and pass
CPUState as argument. Update target-i386 accordingly.

cpu: Introduce get_arch_id() method and override it for X86CPU

get_arch_id() adds possibility for generic code to get a guest-visible
CPU ID without accessing CPUArchState.
If derived classes don't override it, it will return cpu_index.

Override it on target-i386 in X86CPU to return the APIC ID....
