   .def already has an alias mechanism (TRIPLE_VENDOR_ALIAS appears in the vendor rework) — ifTRIPLE_ENV_ALIAS exists too, using it for gnuabin32 would keep the compat spelling in the table itself instead of hand-editingparseEnvironment, which will rebase more cleanly next   

TRIPLE_ENV_ALIAS doesn't exist yet, I checked 23.1.0 and current main. Only the OS and vendor sections have alias macros.

Since Triple.cpp is the only file that includes TripleName.def, the patch can add the macro itself the same way the other two sections
do. I tried it here, the alias line sits in the table next to gnun32 and one extra #define in parseEnvironment replaces the hand edit.
The stack applies clean and llvm builds fine with it.

Is this what you had in mind? I can fold it into v2. We could also send TRIPLE_ENV_ALIAS to llvm as a small NFC patch, then this
carries just two table lines going forward.
