Test more criteria during PVS analysis

This commit:

- Adds a separate analysis run against the MIRSA (Motor Industry
  Software Reliability Association) criteria, which is extremely
  thorough. This tally is not summarized or considered fatal to the
  workflow. It runs virtually instantly, and the results are very
  interesting; however are too numerous to include in our general
  analysis (ie: over 13,000 issues).

- Changes the PVS summary script output to a tally-per-file instead
  of trying to summarize the nature of the issue, which was mostly
  unhelpful without the full text.

- Adds the full list of possible supressible issue to the report
  directory, so if further suppressions are needed then these will be
  easy to find and use.

- Adds one dr_flac suppression per the resolution here:
  mackron/dr_libs#117
