All references to cpu_T are done with a constant index. It aids
readability to decompose the array into two scalar variables.

Having segs[].base as a register significantly improves code
generation for real and protected modes, particularly for TBs
that have multiple memory references where the segment base
can be held in a hard register through the TB.

They are helpers for the ZMMReg fields, so name them accordingly.
This is just a global search+replace, no other changes are being
introduced.

The struct represents a 512-bit register, so name it accordingly.

Backports commit fa4518741ed69aa7993f9c15bb52eacc375681fc from qemu
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.

Writing / reading to model specific registers should be as easy as
calling a function, it's a bit stupid to write shell code and run them
just to write/read to a MSR, and even worse, you need more than just a
shellcode to read...
So, add a special register ID called UC_X86_REG_MSR, which should be
passed to uc_reg_write()/uc_reg_read() as the register ID, and then a
data structure which is uc_x86_msr (12 bytes), as the value (always), where:
Byte Value Size
0 MSR ID 4
4 MSR val 8
* Remove glib from samples makefile
* changes to 16 bit segment registers needs to update segment base as well as segment selector
* change how x86 segment registers are set in 16-bit mode
* more appropriate solution to initial state of x86 segment registers in 16-bit mode
* remove commented lines
