Description
Java crashed while executing method with over 8k of dneg or fneg operations with -Xcomp -server -XX:-DontCompileHugeMethods options on all x86-platforms.

Next two tests failed:
cvm/bytecode/bytecode/dneg 
cvm/bytecode/bytecode/fneg

Jstack output attached to CR.
Issue can be reproduced with all java 7 updates starting from JDK 1.7.0 b148 and all java 6 updates starting from JDK 1.6.0_04 b05.

Issue was not found before because cvm test were added recently.
See comments for more details.

EVALUATION Stack overflow in compiler thread because of very deep recursion (test passed with 5Mb stack -XX:CompilerThreadStackSize=5000). May be we need to replace recursion in remove_globally_dead_node(). But it is not P2.
