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.

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.
