Tracking Issue for `stdarch_arithmetic_ops`

[sayantn]

Feature gate: #![feature(stdarch_arithmetic_ops)]

This is a tracking issue for implementing arithmetic operation traits (in core::ops) for SIMD types in core::arch

Public API

Implementation of the following traits (and the assign variants, if applicable) for all SIMD types that have a defined element size (one exception is __m{128,256,512}i in x86)

• Add
• Sub
• Mul
• Div
• Rem
• Neg

Along with these, the following traits for Integer SIMD types

• BitOr
• BitAnd
• BitXor
• Not
• Shl and Shr (if element size is defined)
