here were 0 and 1 anyway.

This was used only at a single place since commit 3db65ac1
(SystemInformation: wrap the call to CPUID in a function), so there is
no need to keep this abstracted anymore.

In commit bf7f0ddc (Fix KWSys FundamentalType for Universal Binaries,
2009-11-20) we repurposed CMake variables "KWSYS_SIZEOF_${type}" and
dropped use of them from configured headers.  However, use of one was
accidentally left in "IOStream.hxx.in" to record whether the compiler
supports 'long long'.  Replace it with a better test.

Without this, "@KWSYS_SIZEOF_LONG_LONG@" is replaced with "TRUE" which
the preprocessor may evaluate as "0" or "1" depending on whether a
"TRUE" macro is defined.

The CPU may have a TSC but reading it may fail, in which case we now always
fall back to reading the value from the registry. This is especially true
on Windows64 where we do not have the assembler instructions at all.

Remove logic that skips all slashes before the first ':'.  This does not
even make sense for Windows drive letter handling.  While at it, remove
no-op logic that appears to try to remove trailing slashes.

Try to open /proc/cpuinfo only on platforms where it's presence is
expected, namely Linux and Cygwin.

Otherwise try sysconf(_SC_NPROCESSORS_ONLN) as last resort to count
processors. Also account for the slightly different name on IRIX.

-do not always set NumberOfLogicalCPU to 1, it doesn't make any sense
 to have this number smaller than NumberOfPhysicalCPU. Instead keep
 both numbers the same and set LogicalProcessorsPerPhysical to 1.
-replace '/1024*8192/1024' with '/128'

The __aarch64__ defines Aarch64, while __AARCH64EB__ defines bigendian
and __AARCH64EL__ little endian.  Only little endian tested, no big
endian toolchain exists yet.

E.g. Linux ARM platforms write "CPU architecture" instead of "cpu family".
