Change all references to "__INTEL__" to "__i386__".

They are functionally identical, but the former is a BeOS/Haiku-specfic
macro that we include in the compiler specs, and the latter is defined
by GCC.

sysinfo: Refactor CPU feature flag display

* Remove duplicated code
* Add new feature flag field introduced with Ryzen
* Add a few missing Intel cache descriptors
* Don't show 80000007 on Intel. Reserved.
* Clean up language to not show "AMD" flags on Intel

sysinfo: Improve x86 CPU information

* Displays standard CPUID, and shows what the
internal CPUID used by OS.h *should* be.
* Should help out in identifying new CPU's
as all end users have to do is run sysinfo
to get the CPU info + value for OS.h

kernel, libroot: Introduce new API for obtaining system info

sysinfo: Fixed incorrect memory stats on PAE systems.

Memory statistics were calculated as 32-bit values, so they were incorrect
on machines with more than 4GB RAM (and on x86_64).

Fix #9671: sysinfo misses some extended features

Fixed warnings, 80 character line limit.

Support x86_64 in sysinfo.

Just changed all #ifdef __INTEL__ to __INTEL__ || __x86_64__, and
fixed all the printf format strings. The CPU detection code all
works the same.

sysinfo: switch to c++
