Slush: Bug-Fixes Only for Middle End and Primary Platforms

[Mark Mitchell <mark at codesourcery dot com>]

We're in Stage 1, and in Stage 1 big changes happen -- and then there is
naturally some instability.  We clearly have some instability at
present, so we need to slow down until that's resolved.

Therefore, effective immediately, please commit only bug fixes to the
middle end and to architectures that are designated as primary
platforms.  Please hold off on new features for these areas of the
compiler, until things stabilize.  It's OK to continue to add new
features to secondary platforms and front ends, but I suggest that we
exercise caution there as well.  We'll stay in this mode until we've
gotten back to the point where test results are looking pretty good on
all of the primary platforms -- hopefully just a few days.

With the benefit of hindsight, I think that committing both the SSA
expansion and type-checking changes in close succession was probably a
bit too much change a bit too quickly.  When changes of this magnitude
go in, we should probably wait a few days to see if stabilization is
required before introducing another change of large magnitude.

Thank you,
