This function, like its cousin z_tsc_read(), can be shared between
subarches. Note: it's unclear to me if we actually need these to be
two separate functions (do we need serialization?) or if they can
be combined into one function. Add that to the to-do list.

The previous linker script was barebones and non-standard. It is
replaced with a script conforms to the rest of the Zephyr arches,
utilizing include/linker headers and standard macros.
link-tool-gcc.h is updated to account for the "i386:x86-64" arch and
the generation of 64-bit ELF binaries.

Fleshed out z_arch_esf_t and added code to build this frame when

shifted the initialization code to use this instead of the IRQ stack.
Moved IRQ stack(s) to irq.c.

First "complete" version of Intel64 support for x86. Compilation of
apps for supported boards (read: up_squared) with CONFIG_X86_LONGMODE=y
is now working. Booting, device drivers, interrupts, scheduling, etc.
appear to be functioning properly. Beware that this is ALHPA quality,
not ready for production use, but the port has advanced far enough that
it's time to start working through the test suite and samples, fleshing
out any missing features, and squashing bugs.

This patch adds basic build infrastructure, definitions, a linker
script, etc. to use the Zephyr and 0.10.1 SDK to build a 64-bit
ELF binary suitable for use with GRUB to minimally bootstrap an
Apollo Lake (e.g., UpSquared) board. The resulting binary can hardly
be called a Zephyr kernel as it is lacking most of the glue logic,
but it is a starting point to flesh those out in the x86 tree.
The "kernel" builds with a few harmless warnings, both with GCC from
the Zephyr SDK and with ICC (which is currently being worked on in
a separate branch). These warnings are either related to pointer size
differences (since this is an LP64 build) and/or dummy functions
that will be replaced with working versions shortly.

Commit db48d3e22a ("sys_sem: add build time definition macros")
recently introduced SYS_SEM_DEFINE() and defined it in terms of
Z_DECL_ALIGN() and __in_section() to force the _k_sem linker section.
It is however cleaner and less obscur to use Z_STRUCT_SECTION_ITERABLE()
and list the _sys_sem linker section alongside the _k_sem one.

Kinetis SoCs have a 16-byte flash configuration field that must be
loaded at a specific address in flash. This field is not needed if we
are building an image to be chainloaded by MCUboot or a RAM-only image,

System call arguments, at the arch layer, are single words. So
passing wider values requires splitting them into two registers at
call time. This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.
Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths. So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.
Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types. So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*(). The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function. It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.
This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs. Future commits will port the less testable code.
