target-i386: fix {min,max}{pd,ps,sd,ss} SSE2 instructions

minpd, minps, minsd, minss and maxpd, maxps, maxsd, maxss SSE2
instructions have been broken when switching target-i386 to softfloat.
It's not possible to use comparison instructions on float types anymore...

target-i386: fix round{pd,ps,sd,ss} SSE2 instructions

roundps and roundss SSE2 instructions have been broken when switching
target-i386 to softfloat. They use float64_round_to_int to convert a
float32, and while the implicit conversion from float32 to float64 was...

target-i386: fix dpps and dppd SSE2 instructions

The helpers implemented dpps and dppd SSE instructions are not passing
the correct argument types to the softfloat functions. While they do
work anyway providing a correct behaviour, this patch fixes that....

target-i386: fix SSE rounding and flush to zero

SSE rounding and flush to zero control has never been implemented. However
given that softfloat-native was using a single state for FPU and SSE and
given that glibc is setting both FPU and SSE state in fesetround(), this...

kvm: x86: Avoid runtime allocation of xsave buffer

Keep a per-VCPU xsave buffer for kvm_put/get_xsave instead of
continuously allocating and freeing it on state sync.

kvm: x86: Drop redundant apic base and tpr update from kvm_get_sregs

The latter was already commented out, the former is redundant as well.
We always get the latest changes after return from the guest via
kvm_arch_post_run.

kvm: switch kvm slots to use host virtual address instead of ram_addr_t

This simplifies a later switch to the memory API in slot management.
