In order to be able to request Firefox builds with AddressSanitizer support from RelEng, the configuration files need to be added to the tree. The attached patch adds a base configuration in build/unix/mozconfig.asan that can later also be reused for Mac OSX. Furthermore it adds four build specific configs:

my only concern is with these lines here. they'll have to change every time we bump the clang version that's installed. Set these to /tools/clang-3.0 and we'll be good to go once bug 753969 is done.

Updated patch to use Clang symlink

Updated patch with Clang symlink as requested. Carrying r+ from last review. I'd like to land this as soon as the name of the symlink "/tools/clang-3.0" is fixed, even if it does not yet exist. The reason is that others who want to create try builds now, can use these configs easily by substituting the paths and copying the config over the regular linux build configs. I'd also like to point to these configs in the MDN article to make it easier.

Landing this now and will change it later if the symlink turns out to be wrong :)

Anyone know why the Asan builds have -disable-crashreporter?

Crash reporter uses signal handlers that collide with ASan's signal handler. Also, using a crash reporter simply makes no sense when you use ASan, except if our crash reporter was able to deal with the way ASan reports failures.
