Major reorganization and extension of the code. The diff on this will be a
...
mess as functions were moved around into a better ordering. The code was
extended to provide various -gen-* options to better control what the
generated output should be. Currently it is possible to generate entire
modules (three different ways), functions, global variables, and types.

Adjust the interface to ConstantArray::get. The previous

implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.
