Add the new builtin types: int8, uint8, int16, uint16, int32 and uint32.
Support for these new types will need to be bootstrapped over several changes.
This is the first such change and does the following:
- Extends the compiler to recognise 'int8', 'uint8', 'int16', 'uint16', 'int32'
and 'uint32' as builtin types.
- Extends the set of builtin arithmetic, bitwise and relational operators to
cover the new types.
- Extends all of the code generators to handle new types. There currently lots
of limitations and placeholders marked by 'XXX FIXED SIZE INT'. These will
be lifted in later changes.
- Extends the runtimes to support the new types.
- Adds new modules to the standard library intended to hold the basic
operations on the new types. (These are currently empty and not documented.)
This change does not introduce the two 64-bit types, 'int64' and 'uint64'.
Their implementation is more complicated and is best left to a separate change.

<http://www.cs.mu.oz.au/mercury/information/deep_demo.html>
gives an overview of what deep profiling is.
- The deep profiling paper on our web site, "Deep profiling:
engineering a profiler for a declarative programming language"
<http://www.cs.mu.oz.au/mercury/information/papers.html#mu_01_24>
explains in detail what deep profiling is, why it is needed,
and how it is implemented in the Mercury compiler.
- The "Using mdprof" section of the "Profiling" chapter of the
Mercury user's guide explains how to use it.
- The file deep_profiler/notes/deep_profiling.html gives an overview of
the specifics details of our implementation of deep profiling.
