I think that funcs.h is somewhat wrong since it directly
uses the names from the i386 backend (i.e. prologue_xxx).
IMHO it should use the different HAVE_* macros from the
jit3-icode.h to declare the functions (so it correctly
declares prologue_xxx on i386 but prologue_xxC on mipsel).
Furthermore, these declarations should be guarded by
#ifdef HAVE_foo ... #endif for optional things like
HAVE_mon_enter and HAVE_mon_exit.
