[PATCH] D60903: [SampleFDO] Never set profile entry count to 0

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

Looked at the Instruction::updateProfWeight() --- the part that update branch_weights seems bogus  -- there is need need to scale branch weight at all.

VP data needs to be scaled of course, but if 'S' or 'T' is zero, just zero them out.
