[PATCH] x86_64: Icecream has no way of detecting assembler-level includes

Browse source 
Icecream preprocesses c sources locally, and sends the result off to a remote
host for compiling.  It does not recognize includes at assembler level.  The
fix is to put the assemberincludes an a separate .s file, which will always be
assembled locally.
