f327d6d4 - [CIR] Defer definitions of global variables until they are used. (#142496)

[CIR] Defer definitions of global variables until they are used. (#142496) This change adds support for deferring global variable definitions until first use whenever it is possible to do so. Although deferring function definitions uses much of the same implementation, function deferral will be added in a follow-up change.
