Move the disasm.c #included arch files into a new util/annotate-arch directory. Make the code compile standalone. Try to better encapsulate architecture specific code within the files and with a arch__new_ function that allows additional data to be associated with the struct arch using the standard container_of trick. Make the lookup of struct arch use the ELF machine gather from a thread rather than an evsel. For example, the evsel can't determine the difference between EM_386 and EM_X86_64 so generally the latter has currently been used. This means the dwarf registers are off as register 1 is CX with EM_386 and DX with EM_X86_64. To facilitate this change map_symbol is refactored to use a struct thread rather than a struct maps, the maps being obtainable from the thread. To make in and out arguments clearer, for safety, etc. try to constify struct arch and its related structs.
