This patch series adds support for streaming some internal declarations
in C++20 modules that we previously would ICE on.
The series has been successfully bootstrapped and regtested on
x86_64-pc-linux-gnu. Additionally, modules.exp now passes with
'--target_board=unix/-fsanitize=undefined'.
Nathaniel Shead (4):
c++: Add flag to detect underlying representative of bitfield decls
c++/modules: Implement streaming of uncontexted TYPE_DECLs [PR98735]
c++/modules: Support streaming new size cookie for constexpr
[PR120040]
c++/modules: Avoid name clashes when streaming internal labels
[PR98375,PR118904]
