This patch seems to work OK here.  The deform code is a little tricky
as you have to think carefully about which places need TypeDatum and
which need TypeSizeT in llvmjit_deform.c, since the v_offp variable
really is size_t.  Tested on Debian 13 with i386 packages installed.

More changes would be needed if Datum is changed into a struct.
