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.
