[PR] Fix LongJmp pass

Summary:
This patch handles 2 problems with LongJmp pass:
1. The pass should be executed before FinalizeFunctions, since the pass
may add new entry points for the function, and the
BinaryFunction::addEntryPoint has an assert "CurrentState == State::CFG"
2. Replaced shortJmp implementation with position-independent code.
Currently we could handle PIC binaries with max +-4Gb offsets, the
longJmp uses absolute addreses and could could be used only in non-PIE
binaries.
