move fast reject test out of `SelectionContext::match_impl`.
`match_impl` has two call sites. For one of them (within `rematch_impl`) the fast reject test isn't necessary, because any rejection would represent a compiler bug. This commit moves the fast reject test to the other `match_impl` call site, in `assemble_candidates_from_impls`. This lets us move the fast reject test outside the `probe` call in that function. This avoids the taking of useless snapshots when the fast reject test succeeds, which gives a performance win when compiling the `bitmaps` and `nalgebra` crates.
