Handle depolymorphization

[notnotmelon]

Both C++ functions that use templates and member functions on templates classes go through a process known as depolymorphization.

This process creates numerous asm functions which collectively represent all possible instantions of those templates by the compiler.

We cannot reasonably ask users to detour into all of these instances individually. There must be some multi detour mechanism to automatically detour into all instances of a templated function.

Affects both clang and msvc
