Lang Hames 01bc5b7034 [JITLink] Fix sorting bug for PC-begin candidate symbols during EH-frame fixup. ...

The sort should have been lexicographic, but wasn't. This resulted in us
choosing a common symbol at address zero over the intended target function,
leading to a crash.

This patch also moves sorting up to the start of the pass, which means that we
only need to hold on to the canonical symbol at each address rather than a list
of candidates.
