a) how much time it adds to the build?
I have not done extensive testing, but on my Linux workstation with 32
hw threads, building just hotspot release build from a clean workspace
increased maybe 1 or 2 seconds (at around 90s total), but the variance
was around the same amount as that.
b) why this doesn't work for Solaris Studio?
I didn't put a lot of effort into trying to figure it out. The check
used was provided by Kim Barrett, for Linux only. I figured it would be
simple enough to get it to work on mac and succeeded there. It should
certainly be possible to implement a similar check on Solaris, but is it
worth the time to do it? Both development time and increased build time
on one of the slower build platforms?

Hello,
This patch adds a build time check for uses of global operators new
and delete in hotspot C++ code. The check is only run with toolchains
GCC and Clang (Linux and Macos builds). I have also modified the
Oracle devkit on Linux to add the necessary symlink so that objdump
will get picked up by configure.
This change is depending on several fixes removing such uses that are
currently in jdk/hs so this change will need to be pushed there as well.
