[8u] Request for approval for JDK-8169201: Montgomery multiply intrinsic should use correct name

[Aleksey Shipilev]

It is a really trivial patch:
  http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/110b1774a359

diff -r 96e9e479ff8a src/share/vm/opto/library_call.cpp

   assert(UseMontgomeryMultiplyIntrinsic, "not implemented on this platform");
-  const char* stubName = "montgomery_square";
+  const char* stubName = "montgomery_multiply";

   assert(callee()->signature()->size() == 7, "montgomeryMultiply has 7 parameters");


It applies with a bit of fuzz to jdk8-dev.

We need this to avoid weird bugs in code that relies on intrinsic names:
