* [TVMScript] Added unit tests demonstrating desired functionality
* [TVMScript] Implemented parsing of T.Ptr[...]
These can be generated when exporting to TVMscript, but were not
parsable after being generated.
* [TVMScript] Updated buffer_var printing
LetStmt and AllocateNode can both be used to generate handles that are
used in Buffer objects. In these cases, the Buffer declarations must
go after the handle declaration, not in the function header.
* Moved printing of var and buffer_decl into separate statements.
* Updated following @shingjan's review comments.
