Shader serialization experiment (with Mali Offline Compiler analysis) 1) Adds a --writeShaders option to fm. When that's included, the GPU backend is run with a persistent cache (and no binary caching). Then we dump all of the fragment shaders (GLSL for now) that were created to the passed-in directory, along with a JSON digest listing the number of times each one was referenced in the cache. 2) Adds a python script that invokes the Mali Offline Compiler on a directory generated from #1, scraping the output of each compile for cycle counts and writing the collated information to stdout.

Extend --writeShaders to output SPIR-V Changed the python script to operate on all shaders in the directory, handling SPIR-V appropriately, and collating data across backends. Made the output CSV, so that it imports into spreadsheets directly (and handles missing columns cleanly). Removed all the JSON digest logic - this was overkill at the moment, and it made it tricky once we were combining information from GL and Vulkan. Also, the hit count data was probably misleading - it didn't count hits at the program cache level, just the persistent cache.
