  [LLVM][SROA] Teach SROA how to "bitcast" between fixed and scalable vectors. (#130973)

For function whose vscale_range is limited to a single value we can size
scalable vectors. This aids SROA by allowing scalable vector load and
store operations to be considered for replacement whereby bitcasts
through memory can be replaced by vector insert or extract operations.
