boolean indexing segfaults

[simonster]

julia> cat(3, 1, 1, 1)[:, :, [true, true, false]]
fish: Job 1, “julia” terminated by signal SIGSEGV (Address boundary error)

With the original Cartesian commit (626b45b), this fails with:

julia> cat(3, 1, 1, 1)[:, :, [true, true, false]]
ERROR: BoundsError()
 in _F_ at multidimensional.jl:257
 in getindex! at cartesian.jl:74
 in _F_ at multidimensional.jl:39
 in getindex at cartesian.jl:74

Works fine with a1b21bf (last commit before Cartesian). cc @timholy

Seems to be a combination of @inbounds and missing cases for boolean indexing.

Good catch. It turns out we really hadn't been testing logical indexing much, and indeed there was at least one other (long-standing) problem. Perhaps we need to add even more tests, but this should be a start.
