We can't use +PrintInlining flag in 7u40 after 8005031 changes were
backported into 7u40. These changes keep inlining info in GrowableArray
and use GrowableArray::at() method to access elements. Unfortunately in
jdk7u40 at() method is copy constructor vs &at() method which returns
reference in jdk8 (changed for 7200776). As result in jdk7u40 all
changes to inline info are done to local copy and lost.
This problem was reported 2 times. One report (8019313) was from Andreas
Schoesser who did evaluation of the problem and suggested the fix.
I extended his fix to use adr_at() instead of at() in all places where
inlining info is accessed. It will simplify the backport into 7update.
I also added ability to print inlining and intrinsic per method:
