Subject: Remove premature optimization that avoided calculating argument weights
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=bd75021465e7f8c81785e692cfd3ce559764e46f;p=oota-llvm.git

Remove premature optimization that avoided calculating argument weights
if we weren't going to inline the function. The rest of the code using
this was removed.

Fixes PR9154.
