Fix generation of container initializers

The code creates temporary ConstExprValue with global_refs set to
nullptr and that's carried over to the final value. Doing so prevents
the deduplication mechanism to work correctly, causing all sorts of
runtime crashes.

Fixes #1636
Fixes #1608 (Even though it was already fixed by #1991)
