Details

Typed arrays, on trace, have to call a function to convert from a double to an integer.  In many cases the value will actually be an integer to begin with, so we can avoid the function call overhead by checking if i2f(f2i(v)) == v, and if so, just use the f2i(v) value instead of calling a function.
Tracer has been removed.
