`ShaderTranslator.h` and `ShaderTranslator.cpp` files are missing and are not in ANGLE_ROOT/src/libShaderTranslator

Hi! I'm building qemu which depends on ShaderTranslator.h and ShaderTranslator.cpp. There is a shell script, build-ANGLE.sh, supposed to copy them from angle/src/libShaderTranslator to where they are needed. But src/libShaderTranslator is not in angle root dir. Why? Is there a way to get ShaderTranslator.h and ShaderTranslator.cpp? Plz, help me out

I informed ANGLE maintainers too herebut they said I should inform you!
