Subject: [asan] migrate runtime from llvm

Hi,

I create a patch to migrate llvm runtime to asan branch. The
configure.ac is a preliminary version and almost doesn't contain any
portability check. I build it and test my own small case only and it
works. Just send it out to ask for a preliminary review. The patch is
zipped to keep it smaller than 400K (required by sourceware.org).
Because I am a fresh man to gcc, please forgive me to send out a patch
with many errors.

Thanks,
Wei.
