PerformShiftCombine - Checks for immediate versions of vector shifts and lowers them.

As with the vector shift intrinsics, this is done during DAG combining instead of DAG legalizing because the build_vectors for 64-bit vector element shift counts are generally not legal, and it is hard to see their values after they get legalized to loads from a constant pool.

SkipExtensionForVMULL - For a node that is a SIGN_EXTEND, ZERO_EXTEND, ANY_EXTEND, extending load, or BUILD_VECTOR with extended elements, return the unextended value.

The unextended vector should be 64 bits so that it can be used as an operand to a VMULL instruction. If the original vector size before extension is less than 64 bits we add a an extension to resize the vector to 64 bits.

SkipLoadExtensionForVMULL - return a load of the original vector size that does not do any sign/zero extension.

If the original vector is less than 64 bits, an appropriate extension will be added after the load to reach a total size of 64 bits. We have to add the extension separately because ARM does not have a sign/zero extending load for vectors.
