This pull request implements mangling for ConstantMatrixType, allowing matrices to be used on Windows. Related issues: #53158, #127127 This example code: ```cpp #include <typeinfo> #include <stdio.h> typedef float Matrix4 __attribute__((matrix_type(4, 4))); int main() { printf("%s\n", typeid(Matrix4).name()); } ``` Outputs this: ``` struct __clang::__matrix<float,4,4> ```
