  [CIR] Implement lowering for const-emitted global compound literals (#201152)

This came up in a test suite as a NYI, it is just emitting a
constant-backing literal for an initializer. These are specific to C, as
global compound literals have static storage duration in C. This patch,
just like classic codgen, just creates a '.compoundliteral' object as
backing for these variables, and lets us create references to them.
