Commit message:
cmd/compile/internal/noder: encode promoted struct fields for composite literals in UIR
This change requires an encoding format change for struct literals.
Introduce a new UIR version (V3) and use the opportunity to encode
all composite literals more compactly: specifically, when we know
that (composite literal) keys are always present, avoid encoding a
bool value for each key.
Do not yet enable the new format.
For #9859.
