patch applied (ghc): UNDO: Be a little keener to inline

[Simon Peyton-Jones]

Oh my, I'm sorry about that.  I thought I did validate but I certainly did not do stage3.  I do apologise for causing such a strange failure.

The symptoms are deeply strange though --- all it does is inline a bit more, and that should be semantically a no-op.  I'll investigate.

|   This patch caused at least the following test failures:
|      1744(normal)
|      ghci028(ghci)
|      unicode001(normal)
|   and additionally made the stage3 build fail.
|
|   A little more validation please!
|
|   I didn't find the exact cause of the failure yet, but it appears that
|   the Lexer is miscompiled in some strange way.  If any of {Encoding,
|   StringBuffer, or Lexer} are compiled without -O, the problem goes
|   away.
