// We mark certain methods with AggressiveInlining to ensure that the JIT will
// inline them. The JIT would otherwise not inline the method since it, at the
// point it tries to determine inline profability, currently cannot determine
// that most of the code-paths will be optimized away as "dead code".
//
// We then manually inline cases (such as certain intrinsic code-paths) that
// will generate code small enough to make the AgressiveInlining profitable. The
// other cases (such as the software fallback) are placed in their own method.
// This ensures we get good codegen for the "fast-path" and allows the JIT to
// determine inline profitability of the other paths as it would normally.
// Many of the instance methods were moved to be extension methods as it results
// in overall better codegen. This is because instance methods require the C# compiler
// to generate extra locals as the `this` parameter has to be passed by reference.
// Having them be extension methods means that the `this` parameter can be passed by
// value instead, thus reducing the number of locals and helping prevent us from hitting
// the internal inlining limits of the JIT.
