I think this enum should be moved to the macro-assembler, and nop/IsNop should
keep taking int argument. I know that will require that some of the debug break
slot stuff is moved there as well.

Left here as discussed.
Moving this to the Masm was not very convenient because of inlined function and
included files dependencies.
