LLVM 2.6 are the first LLVM version that can run the JIT stable on
ARM/Linux,
previous versions could only run stable on ARM/Darwin.

"Stable" in this context means passing the LLVM regression testsuite
(llvm$ make test).

One benefit for Icedtea to maintain a patch queue for a stable LLVM
release are that all distro maintainers can be sure that all shark -XX
debug options actually work!

For example, currently the only way to make the Shark debug build option
-XX:SharkPrintAsmOf=foo work are to apply Aph's patch on llvm that
enables Shark to set and unset llvm debugging flags multiple times. By
having this queue inside icedtea would help new shark to get access to
all shark options more quickly.

It would also make us more comfortable that we know what configuration
options have been used to build and configure llvm, when we start to
recive bugreports from users.

Yes i would be interested in maintaining a this.
