RFR(M) 8024924: Intrinsify java.lang.Math.addExact

[Vladimir Kozlov]

Rickard,

You need to provide more description for public and include the link to 
the bug report which now is accessible from outside:

https://bugs.openjdk.java.net/browse/JDK-8024924

When result of MathExact is not used we should replace it with top to 
remove uncommon trap.

I think it would be better to create new mathexactnode.?pp files for new 
mathexact nodes. Our *node.?pp files become too fat.

In MultiNode::proj_out(proj) check is_FlagsProj() first since is_Proj() 
is also true for it (since it is subclass).

Next test file misses Copyright header:

test/compiler/8024924/Verify.java

We are moving to creation of subcomponent subdirs for new tests. Could 
you move that into test/compiler/intrinsic/8024924 ?

thanks,
Vladimir
