This continues the effort to get Host code moved over to HostInfo,
and removes many more instances of preprocessor defines along the
way.

inside classes as static local variables and remove the static
ivars. Subclasses should use the accessor functions."
This change moved global statics to function local statics, but
forgot to make the locals static in the function, breaking all
platforms. Furthermore, MSVC doesn't support thread-safe function
local statics, so any use of a function local static on non
primitive types is undefined behavior on MSVC.
Reverting due to the fact that it's broken on all platforms, but
would like to have a discussion about the thread-safety issue
before it goes back in.

This patch creates a HostInfo class, a static class used to answer
basic queries about the host platform. As part of this change,
some functionality is moved from Host to HostInfo, and relevant
fixups are performed in the rest of the codebase.
This is part of a larger effort to isolate more code in the Host
layer into platform-specific groups, to make it easier to make
platform specific changes for a particular Host without breaking
other hosts.
