Code copied from dotnet/corefx

This is code copied out of dotnet/corefx. Do not modify anything under the src subdirectory as it is copied by scripts\UpdateCoreFxCore.ps1 in this repo. The files in the root of this directory are only here to shim out code that the corefx code depends on.

Any changes to code under src in this directory MUST be made in dotnet/corefx as well and should mention Tratcher, anurse and stephentoub.
