TemplateSpecializationType might be sugar for InjectedClassNameType too.

A major source of headaches and probably the source ldc-developers#1 of mapping failures for sophisticated C++ libraries has been the restrictions of D template instantiation scope. Those restrictions are totally necessary and work great in D, and Clang adding "sugar" to its types made it possible to comply with them... most of the time. One particular wall was hit while trying to map the MSVC standard library. For type_traits's conjunction<_Is_character<char>, _Is_character<char>>, the base class in Clang's AST is: TemplateSpecializationType 0xdfaed30 '_Conjunction<struct std::_Is_character<char>, struct std::_Is_character<char> >' sugar _Conjunction | -TemplateArgument type 'struct std::_Is_character<char>':'struct std::_Is_character<char>' | SubstTemplateTypeParmType 0xdda9f20 'struct std::_Is_character<char>' sugar | -TemplateTypeParmType 0xa7ce0f0 '_Traits' dependent contains_unexpanded_pack depth 0 index 0 pack | `-TemplateTypeParm 0xa7ce0c0 '_Traits' `-RecordType 0xa9079d0 'struct std::_Is_character<char>' `-ClassTemplateSpecialization 0xa907930 '_Is_character' | -TemplateArgument type 'struct std::_Is_character<char>' : 'struct std::_Is_character<char>' | SubstTemplateTypeParmType 0xdda9f20 'struct std::_Is_character<char>' sugar (...same as above....) `-RecordType 0xdfaed10 'struct std::_Conjunction<struct std::_Is_character<char>, struct std::_Is_character<char> >' `-ClassTemplateSpecialization 0xdfaec78 '_Conjunction' This is one of those rare cases where Clang has lost pack information and no simple/good heuristic to guess when two or more arguments come from the same pack appears to be possible. Hence either Clang needs to be modified to preserve pack info, or a complicated check/heuristic is needed, or we've got to stop trying to stick to DMD's way. The third option was chosen because there's actually no good reason to comply with those restrictions. Reflection doesn't get improved, and while instantiation from C++ modules, every referenced symbol is from C++ modules. So from now on: - Every type gets desugared before being mapped in non-dependent contexts. - C++ modules now have access to the "C++ global namespace" during name lookups, through a special type of global import. This allows to discard the C++ symbol collector and substitution complicated hack when mapping template arguments deduced by Sema.

I guess the recent removal of module constructors in druntime has brought these to light, for a little LDC ASan smoke test, which newly complains with D v2.105, e.g.: > Direct leak of 78624 byte(s) in 126 object(s) allocated from: > #0 0x55606978c40d in malloc /local/mnt/workspace/tmp/final/llvm-project/compiler-rt/lib/asan/asan_malloc_linux.cpp:145:3 > #1 0x5560698050b1 in _D2rt5minfo11ModuleGroup9sortCtorsMFNbAyaZv
