  1. [ARM] Add the non-MVE instructions in Arm v8.1-M.

    This adds support for the new family of conditional selection /
    increment / negation instructions; the low-overhead branch
    instructions (e.g. BF, WLS, DLS); the CLRM instruction to zero a whole
    list of registers at once; the new VMRS/VMSR and VLDR/VSTR
    instructions to get data in and out of 8.1-M system registers,
    particularly including the new VPR register used by MVE vector

    To support this, we also add a register name 'zr' (used by the CSEL
    family to force one of the inputs to the constant 0), and operand
    types for lists of registers that are also allowed to include APSR or
    VPR (used by CLRM). The VLDR/VSTR instructions also need some new
    addressing modes.

    The low-overhead branch instructions exist in their own separate
    architecture extension, which we treat as enabled by default, but you
    can say -mattr=-lob or equivalent to turn it off.

  2. [DA] Add an option to control delinearization validity checks

    Summary: Dependence Analysis performs static checks to confirm validity
    of delinearization. These checks often fail for 64-bit targets due to
    type conversions and integer wrapping that prevent simplification of the
    SCEV expressions. These checks would also fail at compile-time if the
    lower bound of the loops are compile-time unknown.

  3. [DebugInfo] Terminate all location-lists at end of block

    This commit reapplies r359426 (which was reverted in r360301 due to
    performance problems) and rolls in D61940 to address the performance problem.
    I've combined the two to avoid creating a span of slow-performance, and to
    ease reverting if more problems crop up.

    The summary of D61940: This patch removes the "ChangingRegs" facility in
    DbgEntityHistoryCalculator, as its overapproximate nature can produce incorrect
    variable locations. An unchanging register doesn't mean a variable doesn't
    change its location.

    The patch kills off everything that calculates the ChangingRegs vector.
    Previously ChangingRegs spotted epilogues and marked registers as unchanging if
    they weren't modified outside the epilogue, increasing the chance that we can
    emit a single-location variable record. Without this feature,
    debug-loc-offset.mir and pr19307.mir become temporarily XFAIL. They'll be
    re-enabled by D62314, using the FrameDestroy flag to identify epilogues, I've
    split this into two steps as FrameDestroy isn't necessarily supported by all

    The logic for terminating variable locations at the end of a basic block now
    becomes much more enjoyably simple: we just terminate them all.

    Other test changes: inlined-argument.ll becomes XFAIL, but for a longer term.
    The current algorithm for detecting that a variable has a single-location
    doesn't work in this scenario (inlined function in multiple blocks), only other
    bugs were making this test work. fission-ranges.ll gets slightly refreshed too,
    as the location of "p" is now correctly determined to be a single location.
