[PATCH] Fix PR 71407 : Use correct types for live usage of live operations

[Alan Hayward]

This patch fixes PR 71407 by ensuring the BIT_FIELD_REF is created using
the
given vectype and then casted to the result type.

Tested on x86 and aarch64.
Note that the test vectorizes on x86 but does not vectorize on aarch64 or
power (due to a != statement failing to vectorize)

Ok to commit?
