…hronosGroup#2391) The SPIR-V to LLVM conversion would bail out when encountering an `OpVectorShuffle` whose vector operands differ in size. SPIR-V allows differing vector sizes, but LLVM's `shufflevector` does not. Remove the assert and insert an additional `shufflevector` to align the vector operands when needed. (cherry picked from commit 3df5e38)
