Reduce number of test targets (#2024)
This CL takes the various opt unit tests and makes a single executable
instead of one per test. This reduces the number of build targets by
~125 when building with ninja.

Remove stats use of internal API (#1924)
Instead of using the source/table.h methods, this CL switches the stats
tool to use the spvtools::Context class and assign the message consumer
through the public API.

Move spirv_stats into tools/stats. (#1826)
The spirv_stats code is only used by the tools/stats module. This CL
moves the code to that module.

Cleanup includes. (#1795)
This Cl cleans up the include paths to be relative to the top level
directory. Various include-what-you-use fixes have been added.

Change libspirv to spvtools namespace (#1678)
This CL changes all of the libspirv namespace code to spvtools to match
the rest of the code base.

83228137e1 Re-format source tree - NFC.
Re-formatted the source tree with the command:

$ /usr/bin/clang-format -style=file -i \
    $(find include source tools test utils -name '*.cpp' -or -name '*.h')

This required a fix to source/val/decoration.h.  It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.

78cf86150e Add id descriptor feature to SPIR-V
Id descriptors are computed as a recursive hash of all instructions used
to define an id. Descriptors are invarint of actual id values and
the similar code in different files would produce the same descriptors.

Multiple ids can have the same descriptor. For example
%1 = OpConstant %u32 1
%2 = OpConstant %u32 1
would produce two ids with the same descriptor. But
%3 = OpConstant %s32 1
%4 = OpConstant %u32 2
would have descriptors different from %1 and %2.

Descriptors will be used as handles of move-to-front sequences in SPIR-V
compression.

b4cf371936 Stats analyzer uses validator
Stats analyzer calls validator to check the instruction and update
validator state.

Fixed unit tests (validator was failing).

87a3f651e2 Added Markov chain analysis to stats
Added data structure to SpirvStats which is used to collect statistics
on opcodes following other opcodes.

Added a simple analysis print-out to spirv-stats.

4f216402ba Added statistical analysis tool (tool/stats)
Currently analyzes percentages of the following:
- version (how many 1.0 or 1.1)
- generator
- extension
- capability
- opcode prevalence
