Patch for this issue.

I tried to use NMT with detail option on OpenJDK7 on RHEL6.6, but I got
address at AllocateHeap() as malloc() caller. 

I checked symbol in libjvm.so in OracleJDK8u40 Linux x64, it has
AllocateHeap() symbol. 

AllocateHeap() is defined as inline function, and it gives CURRENT_PC to
os::malloc(). I guess that implementation expects AllocateHeap() will be

It may occur with GCC (g++) optimization only, however I want to fix it
to analyze native memory with NMT on Linux.

This issue has been filed as JDK-8076212, and patch has been accepted to jdk9.
It will be accepted to jdk8u.

Java7 has been EOL, so I want to fix it in IcedTea7 forest.
