If you want the translation of any guest virtual address to guest physical
address then cpu_x86_handle_mmu_fault is close to what you want.  Of
course you'd have to rewrite it as you probably don't want your function
to change the CPU env.

Perhaps cpu_get_phys_page_debug is even closer to what you need,
but I'm not familiar enough with x86 to say for sure.
