Add trace parsing for sanitizer output. The output is different
from debuggerd output (and we do not have control over it). Use
two separate regexes and factor out the parsing into a method
returning a tuple of data.

Note: as we have no control over the prologue of the dump, we
cannot change it to include information like the ABI. Thus, this
functionality only works in a lunched tree, where the tool
implicitly uses the symbols directory.
