on 386 and amd64 because it has not shown an improvement on other platforms.
Hot block alignment can be disabled with `-gcflags=[<packages>=]-d=alignhot=0`

*   XLA Support:
    *   Add standalone XLA AOT runtime target + relevant .cc sources to pip
        package.
    *   Add check for memory alignment to MemoryAllocation::MemoryAllocation()
        on 32-bit ARM. This ensures a deterministic early exit instead of a hard
        to debug bus error later.
