JDK-7147464 - Java crashed while executing method with over 8k of dneg operations
Description
Using tests
cvm/bytecode/bytecode/dneg 
cvm/bytecode/bytecode/fneg
we found compiler issues that could be reproduced if vm was started with option -XX:-DontCompileHugeMethods, because size of those test methods is bigger than corresponding "huge method" threshold. (See JDK-7147464)
But issue described in JDK-7147464 could be also reproduced with similar huge methods with size slightly less than "huge method" threshold.

So at least analogues of cvm/bytecode/bytecode/{dneg,fneg} tests with reduced method size should be created.
