Bug 1337986 - Dump symbols during the compile tier. r=ted This commit moves symbol dumping to the compile tier, to be run via "syms" targets. Tracking files are used for the sake of incremental builds, because dump_syms may genearate multiple outputs whose paths are not known ahead of time. Minimal changes to symbolstore.py are made here. More extensive simplifications will be made in a future commit on the basis of symbolstore.py handling one file at a time. MozReview-Commit-ID: 3mOP8A6Y7iM
