The term for languages like Swift, Java, and Haskell is "obligate GC". The cost of obligate GC is only superficially just the poor memory locality, interruptions, and bad citizenship -- worse is that the power of destructors is denied you, and with it the power to automate managing every other kind of resource. |

These are orthogonal concerns. Plenty of languages without GC do not have good support for ARM (e.g. C), and a GCed language can still have good support for ARM (e.g. monadic regions in Haskell). C++ is really the only language that conflates the two, and IME its RAII style is overrated in practice (there are a lot of rules you have to follow to avoid leaking, and for many of them you get very little warning if you break it).
