Description

See details at https://scan.coverity.com/projects/intel-llvm?tab=overview as CID 490176:

https://github.com/KhronosGroup/SPIRV-LLVM-Translator/blob/590068b12402262dd9bd0aa1386f2e89babfa8a1/lib/SPIRV/SPIRVReader.cpp#L1109

If we don't expect the cast to fail, then we should use cast instead of dyn_cast. The former contains an assertion instead of runtime check

Contributor guide

Research direction
Examine the specific line in SPIRVReader.cpp around line 1109 to confirm that dyn cast can be safely replaced with cast, ensuring no null pointer is expected.
