Move all of the tune files found in conf/machine/include into their
respective architecture directories in that same location. All
references to these will need to be updated. So, change the relevant
ones for this tree in this commit as well.
For the ARM tunes, nest them one further into armv8a, armv8m, etc. and
rename some to make them uniform with the rest of the tunes.

This is the result of automated script conversion:
scripts/contrib/convert-overrides.py <oe-core directory>
converting the metadata to use ":" as the override character instead of "_".

The gcc "corei7" CPU type was last documented in gcc 4.8.x and has
been undocumented from gcc 4.9.x onwards:
https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gcc/i386-and-x86-64-Options.html
https://gcc.gnu.org/onlinedocs/gcc-4.9.4/gcc/i386-and-x86-64-Options.html
Although it still seems to be accepted by gcc 7.x, it's likely to be
deprecated and removed at some point. To preempt that, switch the
corei7 TUNE_CCARGS -march CPU type to "nehalem", which is the closest
replacement (and matches the CPU type already being passed to qemu).
Since the tune-corei7.inc include file is intended to cover a range
of CPUs from Nehalem onwards, switch the TUNE_CCARGS -mtune option
from "corei7" to "generic", which instructs gcc to produce code
optimized for the most common IA32/AMD64/EM64T processors.

Change the name to core2-32 from core2.
There's no AVAILTUNES with the name core2. Make sure that we specify
the correct TUNE name so PACKAGE_EXTRA_ARCHS is expanded correctly.

If tune-corei7 is in use then the target binaries may contain instructions that
qemu-x86-64 can't execute by default, resulting in errors on rootfs construction:
NOTE: Running intercept scripts:
NOTE: > Executing update_font_cache intercept ...
qemu: uncaught target signal 4 (Illegal instruction) - core dumped
In this case the instruction is popcnt, part of SSE4.2, so tell Qemu to emulate
the CPU that the tune targets (in this case, Nehalem). Also pass check=false as
the Nehalem machine supports VME but user-space qemu doesn't, which produces a
warning unless CPUID checking is disabled.

corei7 offers a significant advancement since the previous core2
cpu-type described in the tune-core2 file.
From the GCC(1):
Intel Core i7 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3,
SSSE3, SSE4.1 and SSE4.2 instruction set support.
This offers optimizations for Nehalem and Silvermont (e.g. Bay Trail)
CPUs (and beyond).
