Cullen Rhodes b3e8c4675d [IntrinsicEmitter] Support scalable vectors in intrinsics ... Summary: This patch adds support for scalable vectors in intrinsics, enabling intrinsics such as the following to be defined: declare <vscale x 4 x i32> @llvm.something.nxv4i32(<vscale x 4 x i32>) Support for this is implemented by defining a new type descriptor for scalable vectors and adding mangling support for scalable vector types in the name mangling scheme used by 'any' types in intrinsic signatures. Tests have been added for IRBuilder to test scalable vectors work as expected when using intrinsics through this interface. This required implementing an intrinsic that is explicitly defined with scalable vectors, e.g. LLVMType<nxv4i32>, an SVE floating-point convert intrinsic was used for this. The behaviour of the overloaded type LLVMScalarOrSameVectorWidth with scalable vectors is tested using the existing masked load intrinsic. Also added an .ll test to test the Verifier catches a bad intrinsic argument when passing a fixed-width predicate (mask) to the masked.load intrinsic where a scalable is expected.
