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: 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: 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....
