* Tweak the "sorry" message a bit
- "sorry! (this is work in progress)\n"
+ "sorry! (unimplemented feature or known bug)\n"

* Catch too-large allocations and emit an error message (#4505)
This is a temporary measure until we fix the bug properly (which is
somewhat tricky, and we think might be easier in the new code
generator).
For now we get:
ghc-stage2: sorry! (unimplemented feature or known bug)
(GHC version 7.1 for i386-unknown-linux):
Trying to allocate more than 1040384 bytes.
See: http://hackage.haskell.org/trac/ghc/ticket/4550
Suggestion: read data from a file instead of having large static data
structures in the code.

* fix ticket number (#4505)
