users, and it seems to make more sense to put it here than in the application. All of these are derived from the Tiano code, but I re-wrote the x86_64 one because we use the ELF psABI calling conventions instead of the MS ABI calling conventions. Which is to say you probably shouldn't setjmp()/longjmp() between functions with EFIAPI (aka __attribute__((ms_abi))) and those without.
