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: 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

x86[_64]: Add support for CPUID sub-leaves

Some CPUID leaves may contain one or more sub-leaves accessed by setting
ECX to an appropriate value.

Different uname machine type for x86_64.

* Added B_64_BIT_PC_PLATFORM platform type.
* Return "x86_64" as the machine type for that platform in uname.

Changed ICI data argument types from uint32 to addr_t.

Since ICI arguments are used to send addresses in some places, uint32 is
not sufficient on x86_64. addr_t still refers to the same type as uint32
(unsigned long) on other platforms, so this change only really affects
x86_64.

cpuid: Rework AMD CPUID numbers

* If family is 0xF, we grab extended family and model
like Intel does
* Idenfify AMD cpu's more correctly

*.c -> *.cpp
