Perform two related transforms whose purpose is to incrementally recognize an explode_vector followed by scalar reduction as a vector reduction node.
This exists to recover from a deficiency in SLP which can't handle forests with multiple roots sharing common nodes. In some cases, one of the trees will be vectorized, and the other will remain (unprofitably) scalarized.

Match shuffles that concatenate two vectors, rotate the concatenation, and then extract the original number of elements from the rotated result.
This is equivalent to vector.splice or X86's PALIGNR instruction. The returned rotation amount is for a rotate right, where elements move from higher elements to lower elements. LoSrc indicates the first source vector of the rotate or -1 for undef. HiSrc indicates the second vector of the rotate or -1 for undef. At least one of LoSrc and HiSrc will be 0 or 1 if a rotation is found.
NOTE: We talk about rotate to the right which matches how bit shift and rotate instructions are described where LSBs are on the right, but LLVM IR and the table below write vectors with the lowest elements on the left.

Is this shuffle interleaving contiguous elements from one vector into the even elements and contiguous elements from another vector into the odd elements.
EvenSrc will contain the element that should be in the first even element. OddSrc will contain the element that should be in the first odd element. These can be the first element in a source or the element half way through the source.

Try and optimize BUILD_VECTORs with "dominant values" - these are values which constitute a large proportion of the elements.
In such cases we can splat a vector with the dominant element and make up the shortfall with INSERT_VECTOR_ELTs. Returns SDValue if not profitable. Note that this includes vectors of 2 elements by association. The upper-most element is the "dominant" one, allowing us to use a splat to "insert" the upper element, and an insert of the lower element at position 0, which improves codegen.

Double the element size of the build vector to reduce the number of vslide1down in the build vector chain.
In the worst case, this trades three scalar operations for 1 vector operation. Scalar operations are generally lower latency, and for out-of-order cores we also benefit from additional parallelism.

Given a shuffle where the indices are disjoint between the two sources, e.g.:
t2:v4i8 = vector_shuffle t0:v4i8, t1:v4i8, <2, 7, 1, 4>
Merge the two sources into one and do a single source shuffle:
t2:v4i8 = vselect t1:v4i8, t0:v4i8, <0, 1, 0, 1> t3:v4i8 = vector_shuffle t2:v4i8, undef, <2, 3, 1, 0>
A vselect will either be merged into a masked instruction or be lowered as a vmerge.vvm, which is cheaper than a vrgather.vv.

Match the index of a gather or scatter operation as an operation with twice the element width and half the number of elements.
This is generally profitable (if legal) because these operations are linear in VL, so even if we cause some extract VTYPE/VL toggles, we still come out ahead.

If we have a build_vector where each lane is binop X, C, where C is a constant (but not necessarily the same constant on all lanes), form binop (build_vector x1, x2, ...), (build_vector c1, c2, c3, ..).
We assume that materializing a constant build vector will be no more expensive that performing O(n) binops.

This doesn't try to inspect the widened mask for profitability; we speculate the widened form is equal or better. This has the effect of reducing mask constant sizes - allowing cheaper materialization sequences
