Delete x86_64 ShadowCallStack support

Authored by vlad.tsyrklevich on Mar 6 2019, 11:11 AM.



ShadowCallStack on x86_64 suffered from the same racy security issues as
Return Flow Guard and had performance overhead as high as 13% depending
on the benchmark. x86_64 ShadowCallStack was always an experimental
feature and never shipped a runtime required to support it, as such
there are no expected downstream users.
