[dmd-internals] generating pull requests for DMD

[Don Clugston]

My personal experience:
I run the test suite with only two combinations: no flags, and with -O
-inline -release.  It's only very obscure bugs that aren't detected
with one of those two (personally I've never encountered one, although
I believe they do exist; but failures which are OS-specific are more
common by at least a factor of ten). It takes three minutes to run,
and Phobos takes about two minutes. So it really should not be painful
to run the tests.

If people are not running the tests because they are finding it
difficult or unpleasant, we need to work out why, and fix the problem.
Please speak up!

-Don.
