annotate dmd2/identifier.c @ 1168:ab186e535e72
A different fix to #218 and DMD2682 that does not lead to constant folding regressions.
Fixes run/const_15, run/c/const_16_B.
The price is removing the lvalueness of struct literals. If it turns out too
much code depends on this behavior or we don't want to break with DMD, we
could keep struct literals as lvalues and instead convert struct literals used
as expression initializers into struct initializers.
