8905770b27 compiler.h: replace QEMU_NORETURN with G_NORETURN
G_NORETURN was introduced in glib 2.68, fallback to G_GNUC_NORETURN in
glib-compat.

Note that this attribute must be placed before the function declaration
(bringing a bit of consistency in qemu codebase usage).

b82055aece target/i386: Mark some helpers as noreturn
Any helper that always raises an exception or interrupt,
or simply exits to the main loop, can be so marked.

e7e7bdabab target/i86: implement PKS
Protection Keys for Supervisor-mode pages is a simple extension of
the PKU feature that QEMU already implements.  For supervisor-mode
pages, protection key restrictions come from a new MSR.  The MSR
has no XSAVE state associated to it.

PKS is only respected in long mode.  However, in principle it is
possible to set the MSR even outside long mode, and in fact
even the XSAVE state for PKRU could be set outside long mode
using XRSTOR.  So do not limit the migration subsections for
PKRU and PKRS to long mode.

ed69e8314d i386: move TCG cpu class initialization to tcg/
to do this, we need to take code out of cpu.c and helper.c,
and also move some prototypes from cpu.h, for code that is
needed in tcg/xxx_helper.c, and which in turn is part of the
callbacks registered by the class initialization.

Therefore, do some shuffling of the parts of cpu.h that
are only relevant for tcg/, and put them in tcg/helper-tcg.h

For FT0 and similar macros, put them in tcg/fpu-helper.c
since they are used only there.
