Yes, especially when they're trivial. The cases that just map to an llvm intrinsic add system complexity for no benefit.

Fundamentally we should be treating it more as a runtime library for the compiler and not a user facing abstraction. Right now it's trying to act like a user library or libm and compiler-rt all at the same time when they have different/incompatible constraints.
