We have been using //-switch-inst-prof-update-wrapper-strict// set to //true// by default for some time.
It is time to remove the safety stuff and make //SwitchInstProfUpdateWrapper// intolerant to inconsistencies in !prof branch_weights metadata of //SwitchInst//.
This patch gets rid of the //Invalid// state of //SwitchInstProfUpdateWrapper// and the option //-switch-inst-prof-update-wrapper-strict//.
So there is only two states: //changed// and //unchanged//.
