    gdb: fix frame passed to gdbarch_value_to_register in value_assign

    Commit 78f2fd84e83 ("gdb: remove VALUE_REGNUM, add value::regnum")
    introduced an unexpected change in value_assign.  It replaced
    `get_prev_frame_always (next_frame)` with `next_frame`in the call to
    gdbarch_value_to_register.

    This is the result of a merge error, since I previously had a patch to
    change gdbarch_value_to_register to take the next frame, and later
    decided to drop it.  Revert that change.

    Add a test based on the DWARF assembler to expose the problem and test
    the fix.  I also tested on ppc64le to make sure the problem reported in
    PR 31231 was fixed.
