  -----------
  [CIR] Use zero-initializer for partial array fills (#154161)

If an array initializer list leaves eight or more elements that require
zero fill, we had been generating an individual zero element for every
one of them. This change instead follows the behavior of classic
codegen, which creates a constant structure with the specified elements
followed by a zero-initializer for the trailing zeros.
