b891845b53 Refine the DefUseManager 
* Fix the behavior when analyzing an individual instruction:
  * exisiting instruction:
      Clear the original records and re-analyze it as a new instruction.
  * new instruction with exisiting result id:
      Clear the original records of the exisiting result id. This means
      the records of the analyzed result-id-defining instruction will be
      overwritten by the record of the new instruction with the same
      result id.
  * new instruction with new result id or without result id:
      Just update the internal records to incorperate the new
      instruction.
* Add tests for analyzing individual instruction w/o an exisiting module.
* Refactor ClearInst() implementation
* Remove ClearDef() function.
* Fixed a bug in DefUseManager::ReplaceAllUsesWith() that OpName
  instruction may trigger the assertion incorrectly.
* update the blurbs for EraseUseRecordsOfOperandIds()

b65124f097 Make clear that we are using ptrdiff_t as the iterator difference type. 
And ptrdiff_t is a implementation defined signed type. Comparing it
with unsigned number literal causes compiler warnings.

9747d33d08 Derive iterator from std::iterator to reap standarad algorithms. 
By deriving from std::iterator, iterator_traits will be properly
set up for our custom iterator type, thus we can use algorithms
from STL with our custom iterators.

996a814ae3 Add spirv-cfg to dump a GraphViz graph of the CFG 
This is experimental, and has not tests.
It's been used to debug validation of structured control flow.

- Has a legend describing special arcs to merge blocks and continue
  targets.
- Labels the function entry block, with the Id of the function.

80c94a4fa8 Change the interfaces of in-memory representation to use pointers. 
Previously we use vectors of objects and move semantics to handle
ownership. That approach has the flaw that inserting an object into
the middle of a vector, which may trigger a vector reallocation,
can invalidate some addresses taken from instructions.

Now the in-memory representation internally uses vector of unique
pointers to handle ownership. Since objects are explicitly heap-
allocated now, pointers to them won't be invalidated by vector
resizing anymore.

This is because some old visual studio versions (e.g., 2013) do
not support automatically generating move constructors/assignments.
