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".

GetExtendedProcessorName() may sometimes return "Unknown family" when
we could return something more meaningful. Some systems (e.g. PA-RISC
on Linux) export a "cpu" value in /proc/cpuinfo that has a beautified
processor name in it (e.g. "PA8600 (PCX-W+)"). If we have not found
something nice but this field is present use that information.

If the given key (e.g. "cpu") is matched at the beginning of any line the value
was returned regardless if that line would be the correct match (e.g.
"cpu family" is not the correct line). Make sure between the key and the colon
are only spaces and tabs.

Non-x86 architectures (namely PA-RISC) may not have the "cache size" line, but
others. Search for all and sum up their results.

The Registry class is not used by any other part of KWSys or by any of
the major dependent projects (CMake, ITK, VTK, ParaView, etc.).  Remove
it from KWSys proper.  It can be kept in a specific dependent if
necessary.

Some compilers, notably Clang, will warn at compile time (or
runtime with debug flags) if they detect a null dereference.
Try to outsmart them by dereferencing an address a little
larger than NULL.
