[PATCH 2/4] x86: Move instruction decoder data into header

[Sasha Levin]

Right now we generate data for the instruction decoder and place it
as a code file which gets #included directly (yuck).

Instead, make it a header which will also be usable by other code
that wants to use the data in there.
