This replaces the desc_empty macro with an inline. It now handles
easily any of the four different types used between 32/64 code to
refer to these 8 bytes. It's identical in both asm-x86/processor_64.h
and asm-x86/processor_32.h, so if these files ever get merged this
function can be in the common code.
This also removes the desc_equal macro because nothing uses it.
