Rhys Perry ee073cb543 nir/load_store_vectorize: improve vectorization with identical operations 
We might have several identical options to vectorize an entry with, but
only one might be vectorizable because of writes interfering.

An example of this is a pattern found in some CTS tests:
a = load(0)
b = load(4)
store(0, a)
store(4, b)
a = load(0)
b = load(4)
store(0, a)
store(4, b)
...

It might have attempted to vectorize the first load(0) with the second
load(4) without attempting the second load(4) when the first fails. This
changes vectorize_entries() to continue even if the first try_vectorize()
failed.
