avx512_vpopcntdq: AVX-512 AVX-512 Vector Population Count Doubleword and
Quadword Instructions
avx512_bf16 : AVX-512 BFLOAT16 instructions
la57 : 57-bit virtual address support (5-level Page Tables)
vnmi : Virtual NMI (VNMI) allows the hypervisor to inject the NMI
into the guest without using Event Injection mechanism

the IRET.
auto-ibrs : The AMD Zen4 core supports a new feature called Automatic IBRS.
It is a "set-and-forget" feature that means that, unlike e.g.,
s/w-toggled SPEC_CTRL.IBRS, h/w manages its IBRS mitigation
resources automatically across CPL transitions.

Add the following feature bits.
amd-psfd : Predictive Store Forwarding Disable:
PSF is a hardware-based micro-architectural optimization
designed to improve the performance of code execution by
predicting address dependencies between loads and stores.
While SSBD (Speculative Store Bypass Disable) disables both
PSF and speculative store bypass, PSFD only disables PSF.
PSFD may be desirable for the software which is concerned
with the speculative behavior of PSF but desires a smaller
performance impact than setting SSBD.
Depends on the following kernel commit: b73a54321ad8 ("KVM: x86: Expose Predictive Store Forwarding Disable")

Single Thread Indirect Branch Prediction mode has enhanced
performance and may be left always on.

Introduce new EPYC cpu versions: EPYC-v4 and EPYC-Rome-v3.
The only difference vs. older models is an updated cache_info with
the 'complex_indexing' bit unset, since this bit is not currently
defined for AMD and may cause problems should it be used for
something else in the future. Setting this bit will also cause
CPUID validation failures when running SEV-SNP guests.

New EPYC CPUs versions require small changes to their cache_info's.
Because current QEMU x86 CPU definition does not support versioned
cach_info, we would have to declare a new CPU type for each such case.
To avoid the dup work, add "cache_info" in X86CPUVersionDefinition",
to allow new cache_info pointers to be specified for a new CPU version.

While the old type was correct in the ideal sense, some ABIs require
the argument to be zero-extended. Using uint32_t for all such values
is a decent compromise.

Unify all computation of argument stack offset in one function.
This requires that we adjust ref_slot to be in the same units,

tcg/sparc64: Drop is_64 test from tcg_out_qemu_ld data return
In tcg_canonicalize_memop, we remove MO_SIGN from MO_32 operations
with TCG_TYPE_I32. Thus this is never set. We already have an
identical test just above which does not include is_64

tcg/riscv: Rationalize args to tcg_out_qemu_{ld,st}
Interpret the variable argument placement in the caller. Pass data_type

The port currently does not support "oversize" guests, which
means riscv32 can only target 32-bit guests. We will soon be
building TCG once for all guests. This implies that we can
only support riscv64.
Since all Linux distributions target riscv64 not riscv32,
this is not much of a restriction and simplifies the code.
The brcond2 and setcond2 opcodes are exclusive to 32-bit hosts,
so we can and should remove the stubs.
