Backports commit b216aa6c0fcbaa8ff4128969c14594896a5485a4 from qemu
Existing definition triggers the following when using clang
-fsanitize=undefined:
hw/intc/apic_common.c:314:55: runtime error: left shift of 1048575 by 12
places cannot be represented in type 'int'
Fix it so we won't try to shift a 1 to the sign bit of a signed integer.

The field doesn't need to be inside CPUState, and it is not specific for
the CPUID instruction, so move and rename it.

Instead of putting extra logic inside cpu.h, just do everything inside
cpu_x86_init_user().

Right now, the AVX512 registers are split in many different fields:
xmm_regs for the low 128 bits of the first 16 registers, ymmh_regs
for the next 128 bits of the same first 16 registers, zmmh_regs
for the next 256 bits of the same first 16 registers, and finally
hi16_zmm_regs for the full 512 bits of the second 16 bit registers.
This makes it simple to move data in and out of the xsave region,
but would be a nightmare for a hypothetical TCG implementation and
leads to a proliferation of [XYZ]MM_[BWLSQD] macros. Instead,
this patch marshals data manually from the xsave region to a single
32x512-bit array, simplifying the macro jungle and clarifying which
bits are in which vmstate subsection.
The migration format is unaffected.
