added the NI prints for the array literal

There was a mistake: Store array instructions should print an NI
instruction.

Runs the proper version of the compiler.

These examples serve as tests

Checked out from EX3 to make tests pass

Fixed manually:
- function.teal0.expected
- nonnull-local.teal1.expected
- nonnull-global.teal1.expected

The ASTNode locations were not correct. We fixed them

The file
compiler/testfiles/semacheck/teal1/nonnull-local.teal3.expected
is intentionally empty.

This check is TEAL-1 specific, as TEAL-0 does not have qualifiers
and TEAL-3 implements them in another way.

The file
compiler/testfiles/semacheck/teal1/nonnull-global.teal3.expected
is intentionally empty (since nonnull is a name error in TEAL-3).

Remove code duplication between TEAL-0 and TEAL-3 IR implementations.

The qualifiers are attched to the array object and are checked
dynamically, each time an element is assigned.
