Matthias Gehre dd117cf01d cppcoreguidelines-pro-bounds-constant-array-index: ignore implicit constructor 
Summary:
The code

  struct A {
    int x[3];
  };

gets an compiler-generated copy constructor that uses ArraySubscriptExpr (see below).
Previously, the check would generate a warning on that copy constructor.
This commit disables the warning on implicitly generated code.
AST:

  |-CXXConstructorDecl 0x337b3c8 <col:8> col:8 implicit used constexpr A 'void (const struct A &) noexcept' inline
  | |-ParmVarDecl 0x337b510 <col:8> col:8 used 'const struct A &'
