yangguo c78d7fa1ae Link type feedback vectors to the shared function info. 
Previously, both type feedback vector and the shared function info
of a function points to the matching type feedback metadata. This
makes finding the shared function info of a type feedback vector
difficult.

Instead, we now point the type feeback vector to the shared function
info, and find the metadata through the shared function info.

Also remove the obsolete empty type feedback vector.
