Remove SetContextMessageConsumer from markv_codec_test (#1926)
This CL removes the use of SetContextMessageConsumer from
markv_codec_test and replaces it with a spvtools::Context instead.

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.

250a235a8d Add new compression algorithm and models
Add new "short descriptor" algorithm to MARK-V codec.

Add three shader compression models:
lite - fast, poor compression
mid - balanced
max - best compression

cfd95f3d5a Refactored compression debugger
Markv codec now receives two optional callbacks:
LogConsumer for internal codec logging
DebugConsumer for testing if encoding->decoding produces the original
results.

2401fc0a72 Refactored MARK-V API
- switched from C to C++
- moved MARK-V model creation from backend to frontend
- The same MARK-V model object can be used to encode/decode multiple
files
- Added MARK-V model factory (currently only one option)
- Added --validate option to spirv-markv (run validation while
encoding/decoding)

c25b5bea35 Add SPIRV_SPIRV_COMPRESSION option to cmake
The option is off by default.
cmake -DSPIRV_BUILD_COMPRESSION=ON ..
enables the compression lib, executable, and test build.

Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/834

b36acbec0e Update MARK-V to version 1.01
Includes:
- Multi-sequence move-to-front
- Coding by id descriptor
- Statistical coding of non-id words
- Joint coding of opcode and num_operands

Removed explicit form Huffman codec constructor
- The standard use case for it is to be constructed from initializer list.

Using serialization for Huffman codecs

73e8dac5b9 Added compression tool tools/spirv-markv. Work in progress.
Command line application is located at tools/spirv-markv
API at include/spirv-tools/markv.h

At the moment only very basic compression is implemented, mostly varint.
Scope of supported SPIR-V opcodes is also limited.

Using a simple move-to-front implementation instead of encoding mapped
ids.

Work in progress:
- Does not cover all of SPIR-V
- Does not promise compatibility of compression/decompression across
  different versions of the code.
