Alessandro Di Federico 5009074e9e Introduce AdvancedValueInfo for JT discovery ...

* Introduce `ShrinkInstructionOperandsPass`: a transformation shrinking
  operands and the results of instructions if they are
  zero/sign-extended immediately before and after the instruction.
* Introduce `ConstantRangeSet`: similar to `ConstantRange` but allows
  disjoint ranges.
* Introduce `MaterializedValue`: a class that can represent a constant
  value or a symbol plus offset pair.
* Introduce `DropHelperCallsPass`: a transformation removing calls to
  helpers and replacing them with a function call reading the CSVs that
  the helper reads and writing the CSVs that the helper writes
  (according to CSAA).
* Introduce `DropRangeMetadataPass`: a transformation dropping the
  `range` metadata, which, in certain situations, lowers the quality of
  the results provided by `LazyValueInfo`.
* Introduce `AdvancedValueInfo`: an analysis exploiting results of
  `LazyValueInfo` but collecting them as `ConstantRangeSet` with a
  monotone framework. It produces `MaterializedValue`.
* Anticipate linking of helpers: `AVI` requires `CSAA`, which requires
  helper functions to be linked in.
* Drop `--no-link`.
* Force x86-64 `DataLayout`.
* Reorganize harvesting to either collect simple literals or go with
  (incremental) `AVI`.
* Drop `SET`, `OSRA`, the reaching definition analysis, the
  `SimplifyComparisonsPass` and all the sumjump-related code: e now
  clone `root`, optimize it and analyze it with `AVI`.
* Temporarily drop the `NoReturnAnalysis`.
* Link `libLLVMInstCombine`, `libLLVMCodeGen` and `libLLVMPasses`.
* Introduce tests for `AdvancedValueInfo`,
  `ShrinkInstructionOperandsPass` and `ConstantRangeSet`.
* Fix test results.
* Add `llvm.bswap.i64` and `@pc` to the LLVM template module for unit
  tests.
