Describe the bug

Using material.getName() or materialInstance.getName() always gives an empty value on filament release build, while on debug it returns the name.
I assume it's this line probably being completely optimised away in release mode:

filament/filament/src/details/Material.cpp

Line 200 in 99eac62

UTILS_UNUSED_IN_RELEASE bool const nameOk = parser->getName(&mName);

To Reproduce
Steps to reproduce the behavior:

  1. Call getName() in debug and release and compare the output

Expected behavior

It should also return the name in release mode. We need the material name to select the right one from a complex model where guessing the index isn't really feasible.
