- removed all constant versions of vector instructions. The vector code does not use compound constants so there's no need to have instructions for them. 

- fixed: The code generator had no good safeguards for exceeding the maximum amount of registers.

All there was was a handful of pitiful asserts which in production code do nothing at all but generate broken output.
Even worse, the VM was hardwired to at most 255 constants per type per function by storing the constant count in a byte! This has been extended to 65535, but since many instructions only have a byte available for the constant index, a workaround had to be added to do a two-instruction setup if larger indices are needed.
