MFC r330110: Add kernel retpoline option for amd64
Retpoline is a compiler-based mitigation for CVE-2017-5715, also known
as Spectre V2, that protects against speculative execution branch target
injection attacks.
In this commit it is disabled by default, but will be changed in a
followup commit.
MFC r330962: Remove KERNEL_RETPOLINE from BROKEN_OPTIONS on i386
Clang will compile both amd64 and i386 with retpoline.
