a3435cea23 Update documentation for parameter attributes for the syntax change.

6026cbf165 Terminology change: drop 'integral' completely. Now we just have integer, 
which includes i1.  Change the semantics of the various instructions to
support i1 where they didn't before: for example, it is now legal [though
not terribly useful, as it is the same as xor] to add two i1 values.

70f0dbeea5 Clean up usage of "unsigned" and "signed" in the documentation to indicate 
only that specific instructions regard their operands as signed and
unsigned not that the operands *are* signed or unsigned.

c1d50e7137 For PR950: 
Update for signless integer types:
1. Replace [us]byte with i8
2. Replace [u]short with i16
3. Replace [u]int   with i32
4. Replace [u]long  with i64
5. Document the "define" keyword and use it in all examples.
6. Document parameter attributes and how they affect function types.

da1f5b882a For PR950:

have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

6e19f80688 Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.
