After the next patch, we will move the high parts of AVX and AVX512 registers
in the same array as the SSE registers. This will make it impossible to
memcpy an array of 128-bit values in and out of xmm_regs in one swoop.
Use a for loop instead.
Similarly, always use XMM_Q in translate.c. This avoids introducing bugs
such as the one fixed in the previous patch.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form

TCG generates optimized code for i386 repz instructions in single step mode.
It means that when ecx becomes 0, execution of the string instruction breaks
immediately without an additional iteration for ecx==0 (which will only check
ecx and set the flags). Omitting this iteration leads to different
instructions counting in singlestep mode and in normal execution.
This patch disables optimization of this last iteration for icount mode
which should be deterministic.

After the next patch, if a masked PIC interrupts causes CPU_INTERRUPT_POLL
to be set, the CPU will spuriously get out of halted state. While this
is technically valid, we should avoid that.
Make CPU_INTERRUPT_POLL run apic_update_irq in the right thread and then
look at CPU_INTERRUPT_HARD. If CPU_INTERRUPT_HARD does not get set,
do not report the CPU as having work.
Also move the handling of software-disabled APIC from apic_update_irq
to apic_irq_pending, and always trigger CPU_INTERRUPT_POLL. This will
be important once we will add a case that resets CPU_INTERRUPT_HARD
from apic_update_irq. We want to run it even if we go through
CPU_INTERRUPT_POLL, and even if the local APIC is software disabled.

TCG doesn't support VMX, and nested VMX is not enabled by default in the
KVM kernel module.
So, there's no reason to have VMX enabled by default on the core2duo and
coreduo CPU models, today. Even the newer Intel CPU model definitions
don't have it enabled.
In this case, we need machine-type compat code, as people may be running
the older machine-types on hosts that had VMX nesting enabled.

The following CPU features were never supported by neither TCG or KVM,
so they are useless on the CPU model definitions, today:
* CPUID_DTS (DS)
* CPUID_HT
* CPUID_TM
* CPUID_PBE
* CPUID_EXT_DTES64
* CPUID_EXT_DSCPL
* CPUID_EXT_EST
* CPUID_EXT_TM2
* CPUID_EXT_XTPR
* CPUID_EXT_PDCM
* CPUID_SVM_LBRV
As using "enforce" mode is the only way to ensure guest ABI doesn't
change when moving to a different host, we should make "enforce" mode
the default or at least encourage management software to always use it.
In turn, to make "enforce" usable, we need CPU models that work without
always requiring some features to be explicitly disabled. This patch
removes the above features from all CPU model definitions.
We won't need any machine-type compat code for those changes, because it
is impossible to have existing VMs with those features enabled.

The x86_cpu_compat_disable_kvm_features() name was a bit confusing, as
it won't forcibly disable the feature for all CPU models (i.e. add it to
kvm_default_unset_features), but it will instead turn off the KVM
auto-enabling of the feature (i.e. remove it from kvm_default_features),
meaning the feature may still be enabled by default in some CPU models).

This patch fixes instructions counting when execution is stopped on
breakpoint (e.g. set from gdb). Without a patch extra instruction is translated
and icount is incremented by invalid value (which equals to number of
executed instructions + 1).

Only Intel CPUs support hyperthreading. When users select threads>1 in
-smp option, QEMU fixes it by adjusting CPUID_0000_0001_EBX and
CPUID_8000_0008_ECX based on inputs (sockets, cores, threads);
so guest VM can boot correctly. However it is still better to gives
users a warning when such case happens.

with the problematic case fixed.
Note: I will soon switch to a subkey for signing purposes. To verify

This patch introduces cpu_set_fpuc() function, which changes fpuc field
of the CPU state and calls update_fp_status() function.
These calls update status of softfloat library and prevent bugs caused
by non-coherent rounding settings of the FPU and softfloat.
v2 changes:
* Added missed calls and intoduced setter function (as suggested by TeLeMan)

When the "migratable" property was implemented, the behavior was tested
by changing the default on the code, but actually using the option on
the command-line (e.g. "-cpu host,migratable=false") doesn't work as
expected. This is a regression for a common use case of "-cpu host",
which is to enable features that are supported by the host CPU + kernel
before feature-specific code is added to QEMU.
Fix this by initializing the feature words for "-cpu host" on
x86_cpu_parse_featurestr(), right after parsing the CPU options.
