0f98cdd457 arch/x86: tests/cmsis: disable some CMSIS tests in 64-bit mode
The CMSIS layer doesn't like large stacks, and x86 in long mode
requires large stacks, so we disable these tests for now (as was
previously done on the x86_64 port for the same reasons).

640c5a5e95 boards/x86: add Intel64 (64-bit long-mode) QEMU target board
Add qemu_x86_long board (with CONFIG_X86_LONGMODE=y) for testing.

This requires adding support to soc/ia32 for long mode (trivial),
and adding a quick 64- to 32-bit ELF conversion before invoking
QEMU, which apparently doesn't like 64-bit kernel files.

6244676a51 arch/x86: refactor z_do_read_cpu_timestamp32()
This function, like its cousin z_tsc_read(), can be shared between

two separate functions (do we need serialization?) or if they can
be combined into one function. Add that to the to-do list.

3cf1bff71c arch/x86: complete 64-bit linker script
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.

4ddaa59a89 arch/x86: initial Intel64 support
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.

34307a54f0 arch/x86: initial Intel64 bootstrap framework
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.

d8accb55d1 scripts: footprint: Fix pylint warnings
- Remove unused variables and an unused 'sys' import

 - Simplify 'if len(foo) != 0' to 'if foo'. Non-empty lists/dicts/etc.
   are truthy in Python.

 - Use a raw string to fix this warning:

       scripts/footprint/size_report:270:0: W1401: Anomalous backslash
       in string: '\.'. String constant might be missing an r prefix.
       (anomalous-backslash-in-string)

   The issue is that '\.' just happens to work due to not being
   recognized as an escape sequence.

   Escape sequences are not interpreted in raw strings, so they're safer
   for regexes.

 - Replace 'is 0' with '== 0'. 'is' is for testing object identity, and
   0 isn't guaranteed to be a unique object (but always is in practice).
