  [BOLT] Set valid index for functions with profiles

Some of the passes that calculates tentative layout like LongJmp and
Golang are expecting that only functions with valid index will be
located in hot text section. But currently functions with valid profiles
and not set index are breaking this logic, to fix this we can move the
hasValidProfile() condition from AssignSections pass to ReorderFunctions.
