Make rebindable do-notation behave as advertised Adopt Trac #1537. The patch ended up a bit bigger than I expected, so I suggest we do not merge this into the 6.8 branch. But there is no funadamental reason why not. With this patch, rebindable do-notation really does type as if you had written the original (>>) and (>>=) operations in desguared form. I ended up refactoring some of the (rather complicated) error-context stuff in TcUnify, by pushing an InstOrigin into tcSubExp and its various calls. That means we could get rid of tcFunResTy, and the SubCtxt type. This should improve error messages slightly in complicated situations, because we have an Origin to hand to instCall (in the (isSigmaTy actual_ty) case of tc_sub1). Thanks to Pepe for the first draft of the patch.

Move file locking into the RTS, fixing #629, #1109 File locking (of the Haskell 98 variety) was previously done using a static table with linear search, which had two problems: the array had a fixed size and was sometimes too small (#1109), and performance of lockFile/unlockFile was suboptimal due to the linear search. Also the algorithm failed to count readers as required by Haskell 98 (#629). Now it's done using a hash table (provided by the RTS). Furthermore I avoided the extra fstat() for every open file by passing the dev_t and ino_t into lockFile. This and the improvements to the locking algorithm result in a healthy 20% or so performance increase for opening/closing files (see openFile008 test).

TcPat.tcConPat uses equalities instead of GADT refinement * This patch implements the use of equality constraints instead of GADT refinements that we have been discussing for a while. * It just changes TcPat.tcConPat. It doesn't have any of the simplification and dead code removal that is possible due to this change. * At the moment, this patch breaks a fair number of GADT regression tests.

Add DEBUG-only flag -dsuppress-uniques to suppress printing of uniques This is intended only for debugging use: it makes it easier to compare two variants without the variations between uniques mattering. (Of course, you can't actually feed the output to the C compiler or assembler and expect anything sensible to happen!)
