[analyzer] Run remove dead on end of path.
...
This will simplify checkers that need to register for leaks. Currently,
they have to register for both: check dead and check end of path.
I've modified the SymbolReaper to consider everything on the stack dead
if the input StackLocationContext is 0.
(This is a bit disruptive, so I'd like to flash out all the issues
asap.)

Change resolveRelocation parameters so the relocations can find placeholder values in the original object buffer.
...
Some ELF relocations require adding the a value to the original contents of the object buffer at the specified location. In order to properly handle multiple applications of a relocation, the RuntimeDyld code should be grabbing the original value from the object buffer and writing a new value into the loaded section buffer. This patch changes the parameters passed to resolveRelocations to accommodate this need.
