Add a multi_cpu_race helper This makes the test run alone, to increase the chance of a multi-CPU race happening.

Test for #7815 This test differes slightly from the code in the ticket, but the simplification betters the chances of seeing the error. Instead of looking for the error with an additional tranaction, when error appears only one `reset` can complete and the other is blocked on STM raising an exception.

Make the desugarer a tiny bit cleverer on coercions (fixes Trac #7837) The desugarer was generating a redundant box/unbox pair on the LHS of a RULE, which in turn made matching fail. See Note [Simple coercions] in DsBinds.

6:27 AM Changeset in ghc [3ed9baf]ghc-7.6th-new-7.6 by Simon Peyton Jones <simonpj@…>
Merge b737a4 into the 7.6 branch, curing Trac #7748 The caching of goals in the constraint solver led to a equality-constraint loop even in a really simple program! commit b737a45391201fd475b89227ed1d7c9b72b24eea Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Fri Aug 31 10:05:03 2012 +0100 More simplifications to the constraint solver * inert_solved becomes dictionaries-only, inert_solved_dicts * inert_solved_dicts is used only to cache the result of uses of a top level instance declaration, just like inert_solved_funeqs * That in turn simplifies xCtFlavor and rewriteCtFlavor, because they no longer need a "should I cache" parameter. (Moreover the settings for this parameter were very subtle; it's easy to get loops if you cache too much. Caching only top-level instance uses is much safer, and eliminates all these subtle cases.)

Fix the dynflags consistency code It was checking to see whether the hscTarget is HscC or HscLlvm, and changing it to HscC otherwise. But this meant that as well as rejecting HscAsm, it also rejected HscInterpreted and HscNothing. Now we just check whether it's HscAsm.
