Bug 23959 – [REG2.101.0] Copying arrays of types with postblits from varargs broken

@teodutu created dlang/dmd pull request #15295 "Move lowerings to `_d_array{setassign,assign_{l,r}}` to a `LoweredAssignExp` AST node" mentioning this issue: - Move lowerings to `_d_array{setassign,assign_{l,r}}` to a `LoweredAssignExp` AST node This PR does the following: - uses a `LoweredAssignExp` node for assignmets that lower to `_d_arrayassign_{l,r}` - removes the code in `dinterpret.d` that recreates the original `AssigExp` - simplifies `isArrayConstructionOrAssign()` to just `isArrayConstruction()` since assignments are now handled by a separate AST node - fixes issue 23959 Signed-off-by: Teodor Dutu <[email protected]> https://github.com/dlang/dmd/pull/15295

@teodutu created dlang/dmd pull request #15315 "Fix Issue 23959 - Propagate deprecation to `_d_arrayappendcTXImpl` if the calling scope is deprecated" fixing this issue: - Fix Issue 23959 - Propagate deprecation to `_d_arrayappendcTXImpl` if the calling scope is deprecated This is needed if the lowered expression (`arr ~= elem`) is made within a deprecated context to avoid spurious deprecation messages about the hook being emitted.
