Subject : Disable Full-WPO for the x64 official build (non-PGO).
Author  : sebmarchand
Commit description:
  
Disable Full-WPO for the x64 official builds (this doesn't
affect the PGO builds).

This should help me to get an official
"non-PGO & non-WPO" build that I can compare against an official PGO
build.

Also I'm not sure if it's worth keeping WPO turned on for the official
builds at the moment ? We don't ship these builds (we ship the PGO ones)
and so this only slowdown the builders that build an official x64 build
for testing purposes (especially considering that they need to link all the unittests with Full-WPO)
