The indices proc simply creates a vector where each lane contains its own lane index. This can be useful for use in generating masks for loads and stores at the beginning/end of slices, among other things. The new reduce_add/reduce_mul procs perform the corresponding arithmetic reduction, in different orders than just "in sequential order". These alternative orders can often be faster to calculate, as they can offer better SIMD hardware utilization. Two different orders are added for these: pair-wise (operating on adjacent pairs of elements) or split-wise (operating element-wise on the two halves of the vector). This doesn't actually cover the *fastest* way for arbitrarily-sized vectors. That would be an ordered reduction across the native vector width, then reducing the resulting vector to a scalar in an appropriate parallel fashion. I'd created an implementation of that, but it required multiple procs and a fair bit more trickery than I was comfortable with submitting to `core`, so it's not included yet. Maybe in the future.

The Odin Programming Language
Odin is a general-purpose programming language with distinct typing, built for high performance, modern systems, and built-in data-oriented data types. The Odin Programming Language, the C alternative for the joy of programming.
