GHC-LLVM compatibility tests

Here are results from a series of compatibility tests of GHC’s LLVM backend. See the main article for conclusions.

These were taken on an x86-64 EC2 instance running Ubuntu 14.04.1 LTS.

LLVM 3.5, GHC 7.8.3 with rework, internal symbols

Unexpected results from:

    3953 total tests, which gave rise to
   21343 test cases, of which
   19720 were skipped
