52322ac7b9 import-trace: compile with LLVM 3.3
This was necessary because LLVM 3.1's
ELFObjectFile<ELFT>::sectionContainsSymbolsectionContainsSymbol() (needed
for proper functioning of our LLVM disassembler, unless you're using
-ffunction-sections) is "unimplemented".

6c9bb21ab3 import-trace: introduce RandomJumpImporter
The random jump importer defines trace events, that indicate all
possible jumps into a specific instruction range. The region where
jumps should start can be defined by a memory map given with
--jump-from. For each instruction declared in that memory range, all
possible jumps to a memory region specified by with --jump-to are
inserted. The target of the jump is saved in the data_address
field. So all database tools work as expected.

for each event E \in region(--jump-from):
    foreach Instruction in region(--jump-to):
         insert_trace(injection_instr = E.IP(), data_address = Instruction.addr)
