Rollup merge of #55450 - japaric:msp430, r=alexcrichton
msp430: remove the whole Atomic* API
PR #51953 enabled the Atomic*.{load,store} API on MSP430. Unfortunately,
the LLVM backend doesn't currently support those atomic operations, so this
commit removes the API and leaves instructions on how and when to enable it
in the future.
the second fixes compiling liballoc for msp430
closes #54511
