getZeroVector - Returns a vector of specified type with all zero elements.
Zero vectors are used to represent vector negation and in those cases will be implemented with the NEON VNEG instruction. However, VNEG does not support i64 elements, so sometimes the zero vectors will need to be explicitly constructed. Regardless, use a canonical VMOV to create the zero vector.

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.

PerformVMulVCTPCombine - VCVT (fixed-point to floating-point, Advanced SIMD) can replace combinations of VCVT (integer to floating-point) and VMUL when the VMUL has a constant operand that is a power of 2.

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.
