I don't think this if statement does what you think it does. As long as the
intrinsic remains in the MIR you won't be able to proceed with codegen.
instead if you want to gracefully exit you should modify the GLSL version of
`selectExtInst ` to do something like this
```cpp
if (!STI.canUseExtInstSet(SPIRV::InstructionSet::GLSL_std_450)) {
std::string DiagMsg;
raw_string_ostream OS(DiagMsg);
I.print(OS);
DiagMsg = "Intrinsic selection not supported for this instruction set: " +
DiagMsg;
report_fatal_error(DiagMsg.c_str(), false);
}
//original behavior of selectExtInst
```
