cgraphclones.c (localize_profile): New function.
* cgraphclones.c (localize_profile): New function.
(cgraph_node::create_clone): Use it for partial profiles.
* common.opt (fprofile-partial-training): New flag.
* doc/invoke.texi (-fprofile-partial-training): Document.
* ipa-cp.c (update_profiling_info): For partial profiles do not
set function profile to zero.
* profile.c (compute_branch_probabilities): With partial profile
watch if edge count is zero and turn all probabilities to guessed.
(compute_branch_probabilities): For partial profiles do not apply
profile when entry count is zero.
* tree-profile.c (tree_profiling): Only do value_profile_transformations
when profile is read.
