jit: Fix type used for Datum values in LLVM IR.

Commit 2a600a93 made Datum 8 bytes wide everywhere.  It was no longer
appropriate to use TypeSizeT on 32 bit systems, and JIT compilation
would fail with various type check errors.  Introduce a separate
LLVMTypeRef with the name TypeDatum.  TypeSizeT is still used in some
places for actual size_t values.
