Not sure if it is possible or not without having to pass the size
explicitly. This structure is opaque to most of the code in GDB,
and the size is usually only known inside the specific -tdep.c file.
We might be able to work around that by defining a macro instead of
having a function, but it's not clear whether it'd be a real
improvement or not over a call to XZALLOC...
