Add tests for ast optimizations

[Eclips4]

Feature or enhancement

Proposal:

Currently we have a one test case which testing that optimize parameter for ast.parse is working as expected.

I propose to add tests for these ast optimizations:

• Optimization for binary operations if left and right operands are constants
• Optimization for unary operations if operand is constant
• Optimization for in operator if right operand is constant list or set
• Folding of tuples
• Subscription for constant sequences (tuple, string)

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Tests for optimization are included in test_peepholer.

Tests for optimization are included in test_peepholer.

test_peepholer tests that something is present in the bytecode, but it doesn't tell which part of interpreter are responsible for that.
