Add new `mpz_mul_si`-based primop (re #8647) This primop helps reducing allocation by being able to pass one `S#` argument directly to the GMP multiplication primitive without needing to promote (and thus allocate a `ByteArray#` as well) the `J#` first.

Improve the equality-floating story (again), to fix Trac #8644 We float equalities out of implications whose 'givens' include equalities. But it's a bit tricky knowing whether some givens do or do not include equalities, as #8644 shows. There the given has type 'c' (which might have equalities), but we discover that 'c ~ ()', which definitely doesn't. In short, we must look at the givens *after* normalisation, not before. Moreover, something similar happens in approximateWC, where we need to ask whether an implication has given equalities. This patch does the job: * Add a Boolean field inert_no_eqs to InertCans, which records whether we've added a non-constant equality * Add a field ic_no_eqs to Implication, which records whether the ic_given binders include any equalities * Get rid of Inst.hasEqualities altogether On the way I did some un-forced refactoring * Introduce the auxiliary function TcCanonical.flattenNestedFamApp * Kill off FamHeadMap and PredMap in favour of the new FunEqMap and DictMap respectively

Refactor the way shadowing in handled in GHCi If you say ghci> import Foo( T ) ghci> data T = MkT ghci> data T = XXX then the second 'data T' should shadow the first. But the qualified Foo.T should still be available. We really weren't handling this correctly at all, resulting in Trac #8639 and #8628 among others This patch: * Add RdrName.extendGlobalRdrEnv, which does shadowing properly * Change HscTypes.icExtendGblRdrEnv (was badly-named icPlusGblRdrEnv) to use the new function * Change RnNames.extendGobalRdrEnvRn to use the new function * Move gresFrom Avails into RdrName * Better pprGlobalRdrEnv function in RdrName

Improve error message when using qualified names in GHCi When you say ghci> :i Foo.x GHCi tries to find module Foo and get 'x' from it. But if Foo doesn't exist we don't want to say: Attempting to use module ‛Foo’ which is not loaded This is a bit confusing. Rather we just want to say that Foo.x is not in scope.
