`A3-3-1`: missing compliant declarations

[rcseacord]

Affected rules

A3-3-1

Description

Add additional compliant declarations to the test code.

Example

The test file test.cpp is missing some tests.

// I would add the following lines to the text case

const int c = 1;  // COMPLIANT - internal linkage
const char* const str2 = "foo";    // COMPLIANT - internal linkage
constexpr int k = 1;   // COMPLIANT - internal linkage

Most const-qualified objects have internal linkage.
See the [basic.link] subclause of the C++ Standard for additional information.
