Perform Bitcast legalize action on G_EXTRACT_VECTOR_ELT.
Perform a G_EXTRACT_VECTOR_ELT in a different sized vector element.
If this is casting to a vector with a smaller element size, perform multiple element extracts and merge the results. If this is coercing to a vector with larger elements, index the bitcasted vector and extract the target element with bit operations. This is intended to force the indexing in the native register size for architectures that can dynamically index the register file.

Perform Bitcast legalize action on G_INSERT_VECTOR_ELT.
Perform a G_INSERT_VECTOR_ELT in a different sized vector element.
If this is increasing the element size, perform the indexing in the target element type, and use bit operations to insert at the element position. This is intended for architectures that can dynamically index the register file and want to force indexing in the native register size.

Handles most opcodes.
Split MI into same instruction on sub-vectors or scalars with NumElts elements (1 for scalar). Supports uneven splits: there can be leftover sub-vector with fewer then NumElts or a leftover scalar. To avoid this use moreElements first and set MI number of elements to multiple of NumElts. Non-vector operands that should be used on all sub-instructions without split are listed in NonVecOpIndices.
