2021-05-04target/ppc: Remove env->immu_idx and env->dmmu_idxRichard Henderson
We weren't recording MSR_GS in hflags, which means that BookE memory accesses were essentially random vs Guest State. Instead of adding this bit directly, record the completed mmu indexes instead. This makes it obvious that we are recording exactly the information that we need. This also means that we can stop directly recording MSR_IR.

Nothing within the translator -- or anywhere else for that matter -- checks MSR_SA or MSR_AP on the 602. This may be a mistake. However, for the moment, we need not record these bits in hflags.

2021-05-04target/ppc: Disconnect hflags from MSRRichard Henderson
Copying flags directly from msr has drawbacks: (1) msr bits mean different things per cpu, (2) msr has 64 bits on 64 cpus while tb->flags has only 32 bits. Create a enum to define these bits. Document the origin of each bit and validate those bits that must match MSR. This fixes the truncation of env->hflags to tb->flags, because we no longer have hflags bits set above bit 31. Most of the code in ppc_tr_init_disas_context is moved over to hreg_compute_hflags. Some of it is simple extractions from msr, some requires examining other cpu flags. Anything that is moved becomes a simple extract from hflags in ppc_tr_init_disas_context. Several existing bugs are left in ppc_tr_init_disas_context, where additional changes are required -- to be addressed in future patches. Remove a broken #if 0 block.

This appears to be set if and only if POWERPC_FLAG_RTC_CLK is set, but we're not short of bits and having both names will avoid confusion.

Move helper_cache() to tcg/sysemu/special_helper.c. The CACHE opcode is privileged and is not accessible in user emulation. However we get a link failure when restricting the symbol to sysemu. For now, add a stub helper to satisfy linking, which abort if ever called.
