Subject: [PATCH 1/4] [clang][CGRecordLayout] Remove dependency on isZeroSize
This is a follow-up from the conversation starting at
https://github.com/llvm/llvm-project/pull/93809#issuecomment-2173729801
The root problem that motivated the change are external AST
sources that compute `ASTRecordLayout`s themselves instead of
letting Clang compute them from the AST. One such examples is
LLDB using DWARF to get the definitive offsets and sizes of C++
structures. Such layouts should be considered correct (modulo
buggy DWARF), but various assertions and lowering logic around
the `CGRecordLayoutBuilder` relies on the AST having
`[[no_unique_address]]` attached to them. This is a layout-altering
attribute which is not encoded in DWARF. This causes us LLDB to trip
over the various LLVM<->Clang layout consistency checks. There has been
precedent for avoiding such layout-altering attributes to affect
lowering with externally-provided layouts (e.g., packed structs).
This patch proposes to replace the `isZeroSize` checks in
`CGRecordLayoutBuilder` (which roughly means "empty field
with [[no_unique_address]]") with checks for
`CodeGen::isEmptyField`/`CodeGen::isEmptyRecord`.
