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.

485f513a29 Manually create move the constructor/assignment for Instruction. 
This is because some old visual studio versions (e.g., 2013) do
not support automatically generating move constructors/assignments.

190b0d3162 Use NEW behavior for policy CMP0054. 
The NEW behavior is to not dereference variables or interpret keywords
that have been quoted or bracketed.

For more information, see
https://cmake.org/cmake/help/v3.1/policy/CMP0054.html.

This is to suppress a warning when using CMake 3.1.3+.

b51b80980c Validator cfg fixes 
- Find unreachable continue targets.  Look for back edges
  with a DFS traversal separate from the dominance traversals,
  where we count the OpLoopMerge from the header to the continue
  target as an edge in the graph.

- It's ok for a loop to have multiple back edges, provided
  they are all from the same block, and we call that the latch block.
  This may require a clarification/fix in the SPIR-V spec.

- Compute postdominance correctly for infinite loop:
  Bias *predecessor* traversal root finding so that you use
  a later block in the original list.  This ensures that
  for certain simple infinite loops in the CFG where neither
  block branches to a node without successors, that we'll
  compute the loop header as dominating the latch block, and the
  latch block as postdominating the loop header.
