Add support for getting executable memory on Windows. This is actually

much easier than on unix. :) The only evil thing is that windows.h defines
a macro named FindExecutable, which collides with one of our names.
The JIT now runs on windows, but it cannot resolve external functions

Part of bug 122:

This change removes the BuildBytecodeInfo flag from the SlotCalculator
class. This flag was needed to distinguish between the Bytecode/Writer
and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can
remove this flag and simplify some code. Also, some minor name changes
to CachedWriter.h needed to be committed (missed in previous commit).

Adding the initial implementation of the SlotTable class. This class is

the Abstract Data Type that holds slot number values and associates them

numbers and provides a controlled interface for building the table. It does
not enforce any particular idiom or functionality for manipulating the slot
numbers.
This is part of bug_122. The SlotCalculator and SlotMachine classes will
follow.
