    pan/bi: Align staging registers on Valhall
    
    This handles the following from the Valhall specification (that I wrote):
    
        If multiple subsequent staging registers are accessed, the base must
        be aligned to 2. However, even if 4 registers are accessed, it is
        not necessary to align to 4, only to 2. This restriction allows the
        hardware to use a 64-bit data path without handling unaligned
        access, which is more efficient. This restriction does not apply if
        only a single register is accessed.

    pan/bi: Clean up and export bi_reconverge_branches
    
    Decides when we need "branch reconvergence" (canonical term), the
    logical opposite of "back-to-back execution" (non-canonical term, this
    is old code in Bifrost terms). So invert the return value, rename, and
    export so we can use it when packing Valhall instructions.

    pan/bi: Add strip_index helper
    
    Needed to correctly lower sources to moves, used in the FAU lowering.
    Technically, the issue is already present on Bifrost, but it's hidden
    because Bifrost packing doesn't validate the absense of unsupported
    modifiers. Valhall packing adds more safety, which caught this issue.
