(Binary Analysis) Fixed use-def bug in symbolic semantics

* Current instruction was sometimes added as a definer when it
  shouldn't have been added.
(Binary Analysis) Updated use-def answers
(Binary Analysis) Changed filter for semantics test results

* The old filter wasn't working because the size of the address
  replacement text depended on the size of the original address,
  which varied across machines (and probably even runs on the
  same machine).
(SQLite3) Fixed compile error on 32-bit platforms
(Binary Analysis) Fixed compile error for 32-bit platforms
(Binary Analysis) Replaced a couple HT with SP
(Binary Analysis) Fixed a test filter bug
Fixed bug in support for Chombo example code and two bugs for Jeff.
Fixed bug in support for Chombo example code and two bugs for Jeff (added associated test codes).
Added initial version of frontierDetection for token stream unparsing.
Added initial version of frontierDetection for token stream unparsing.
Removed some output spew from generated code and now supporting initial token unparsing frontier work.
Merge remote branch 'rc/master' into clone-detection
Fixed bug caught by tests/roseTests/astInterfaceTests.
Merge remote-tracking branch 'origin/master' into dq-edg4x-rc
Fixed bug caught by tests/roseTests/loopProcessing.
(Binary Analysis) Fixed usedef answer filter

This filter was comparing memory addresses by replacing the address
digits with "x" characters, but that approach doesn't work because
the code that prints the original address does not use a fixed-length
format.

This commit fixes the problem by just removing the entire address.
Fixed bug in build function buildDefiningFunctionDeclaration() which added non-defining declaration to scope.
Merge remote-tracking branch 'origin/master' into HEAD
(Binary Analysis) Added --base-va switch to disassembler

* The entire specimen can be rebased by supplying an alternate base
  virtual address.  This doesn't work perfectly for file formats that
  don't natively support a base address (e.g., ELF) or specimens
  that support a base address but do not contain position independent
  code.

* Fixed one place in the Partitioner to account for non-zero base_va
  for ELF files.
