Fix bugs in the Aditi bytecode output routines.
compiler/bytecode.m:
compiler/bytecode_data.m:
Move the data conversion predicates from bytecode.m to a new module
so they can be used by for output of Aditi-RL bytecode in the
compiler and in the RL bytecode assembler in the Aditi distribution.
Add new predicates to convert integers and floats to lists of
bytes rather than writing them out immediately.
compiler/rl_code.m:
Use the same data conversion predicates for Aditi-RL
bytecodes as for Mercury bytecodes.
This fixes a bug with the output of integers on 32 bit machines
(integers were being shifted by more than the width of the type,
the result of which is undefined) and endianness problems with
floating point numbers.
