This forks the testing harness from https://github.com/google/shaderc to allow testing CLI tools. New features needed for SPIRV-Tools include: 1- A new PlaceHolder subclass for spirv shaders. This place holder calls spirv-as to convert assembly input into SPIRV bytecode. This is required for most tools in SPIRV-Tools. 2- A minimal testing file for testing basic functionality of spirv-opt. Add tests for all flags in spirv-opt. 1. Adds tests to check that known flags match the names that each pass advertises. 2. Adds tests to check that -O, -Os and --legalize-hlsl schedule the expected passes. 3. Adds more functionality to Expect classes to support regular expression matching on stderr. 4. Add checks for integer arguments to optimization flags. 5. Fixes #1817 by modifying the parsing of integer arguments in flags that take them. 6. Fixes -Oconfig file parsing (#1778). It reads every line of the file into a string and then parses that string by tokenizing every group of characters between whitespaces (using the standard cin reading operator). This mimics shell command-line parsing, but it does not support quoting (and I'm not planning to).
