Fix code generation for real expressions
...
Real value are vector width of 1, fix real literal to reflect this.
fix leaking real registers in code generation for function arguments.
Load of signal should handle conversion from real to vector. Function
arguments, type vector passed a real value, are an example where this
comes up.

Major rework of array handling. Memories are replaced with the

more general concept of arrays. The NetMemory and NetEMemory
