Protect against out-of-bounds references when folding OpCompositeExtract (#2774)

This fixes #2608.

The original test case had an out-of-bounds reference that ended up
folding into OpCompositeExtract that was indexing right outside the
constant composite.

The returned constant would then cause a segfault during constant
propagation.
