RFR: JDK-8134157: adlc fails to compile with SS12u4

[Erik Joelsson]

Hello,

We are working towards upgrading the officially supported compilers for 
JDK 9 and on Solaris, the proposed new compiler is Solaris Studio 12 
update 4. When attempting to build with that compiler, the hotspot build 
fails very early with:

"/opt/jprt/jprtadm/erik/jdk9-dev/hotspot/src/share/vm/adlc/adlparse.cpp", line 
2331: Error: Could not find source for 
RegisterForm::addRegClass<RegClass>(const char*).

This can be worked around by adding -template=extdef to the compiler 
flags. I propose we add this just when compiling adlc and for this 
particular version of Solaris Studio. See bug for further discussion of 
the issue.
