// darwinSupportsAVX512 checks Darwin kernel for AVX512 support via sysctl

// Background:
// Darwin implements a special mechanism to economize on thread state when

// preempting threads that haven't yet used any AVX512 instructions, but adds

// via sysctl call or commpage inspection). See issue 43089 and link below for

// file per direct import. However, it meant that the files tended to
// get larger based on the level of the package in the import
// graph. For example, higher-level packages in the kubernetes module
// have over 1MB of "deep" export data, even when they have almost no
// content of their own, merely because they mention a major type that
// references many others. In pathological cases the export data was
// 300x larger than the source for a package due to this quadratic
// growth.
//
// "Shallow" export data means that the serialized types describe only
// a single package. If those types mention types from other packages,
// the type checker may need to request additional packages beyond
// just the direct imports. Type information for the entire transitive
// closure of imports is provided (lazily) by the DAG.
