Cullen Rhodes 2ba5d64a80 [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.
