The magic macro DEF_NATIVE() in the paravirt patching code uses inline
assembly to generate a data table for patching in the native instructions.

While clever this is falling apart with LTO and even aside of LTO the
construct is just working by chance according to GCC folks.

Aside of that the tables are constant data and not some form of magic
text.

As these constructs are not subject to frequent changes it is not a
maintenance issue to convert them to regular data tables which are
initialized with hex bytes.

Create a new set of macros and data structures to store the instruction
sequences and convert the code over.
