Fix compressed assignments to concatenations.

When loading a lval concatenation, tgt-vvp was loading the elements
in the wrong order for the %concat instruction.

Make .scope aware of return type, and extend %ret/vec4 operands
...
The .scope needs to be aware of return types so that the %call/vec4
function knows how to intialize the return value. We also need to
extend the %ret/vec4 to support writing parts of the return value.

Add ability to read back return value / Add vec4 stacked user functions.

- Cleanup detect of signal as return value.

Fix for br999 - incorrect result from binary comparison.
...
When a binary (in)equality comparison has a constant left operand,
the tgt-vvp code generator swaps the left and right operands to
allow the cmpi instruction to be used. The code for swapping the
operands was incorrect.

Rework user function calls to use specialized opcodes.
...
Create The %callf/* opcodes to invoke user defined functions in a
more specialized way. This allows for some sanity checking on the
way, and also is a step towards keeping return values on stacks.

Use cmpi in more cases
...
Before this patch, only literals on the right side of a < compare
(or left side of a > compare) would be blended into a %cmpi instruction.
This patch broadends the cases where the %cmpi can be used.
