Don't rely on VectorType::get() default parameter
Don't rely on VectorType::get() default parameter

LLVM 11 deprecates the default boolean parameter which indicates whether
vector types are variable-length. Explicitly pass 'false'.

LLVM 11 introduces a FixedVectorType for this as well, which would help
readability, but we're still at LLVM 10.
