The blitter has a cache which can allow us to reuse already used
routines, so it should be kept in a central location. For that
reason, the blitter ownership was moved from the Image object to
the Device object.

Regress is a tool that detects test regressions with SwiftShader changes.

Regres monitors changes that have been put up for review with Gerrit.
Once a new patchset has been found, regres will checkout, build and test the change against the parent changelist. Any differences in results are reported as a review comment on the change.

tests/regres/full-tests.json contains a full test list that will be run
once every day. The results of this full test pass will update the
test lists binned by status (*-PASS.txt, *-FAIL.txt, etc).

tests/regres/ci-tests.json references just the *.PASS.txt lists, and
will be run for every change up for review.

The goal of this refactor is to significantly speed up the regres test
cycles. The side effect of this is that regres will no longer
automatically tell you when a single change passes new tests. It will
however tell you when you break tests. The daily test will show you new
tests that are passing, and gives a simple way to see all tests by
status.

There's little point in continuing beyond an unimplemented instruction

If you get unlucky, you wander off into undefined behavior.

LLVM/Clang toolchain emits more warnings.  Since `third_party/llvm-7.0`

we are disabling implicit fallthrough warnings before it has been fixed
