Ben L. Titzer 99484e23cb [wasm] Intrinsify math imports 
This CL adds new Wasm import call kinds that correspond to various
math functions that can be imported from JavaScript, such as trigonometry.
Instead of calling a special import wrapper that converts arguments
to tagged values by boxing, we can now generate calls to little WASM
stubs that contain a single WASM bytecode each.
