// pass, and returns a memfile (is_memfile=true, readall=true) whose payload

// has been placed in memory of the requested `type`.

// When `allow_high_mem` is true and the target architecture is i386, the

// buffer may end up above 4 GiB; in that case the returned handle has

// is_high_mem=true, fd=NULL, and load_addr_64 holding the physical address.

// Otherwise load_addr_64 == (uintptr_t)fd. On i386 the two memcpy callbacks

// are used only when allow_high_mem is true; pass NULL otherwise.
