testsuite: Update some vect cases for partial vectors
This patch is to adjust some existing vectorization test cases
to work well with the newly introduced partial vector usages.
Bootstrapped/regtested on aarch64-linux-gnu and powerpc64le-linux-gnu
P9 (with explicit param vect-partial-vector-usage=1 and enablement on
check_effective_target_vect_partial_vectors_usage_1 check).
gcc/ChangeLog:
* doc/sourcebuild.texi (vect_len_load_store,
vect_partial_vectors_usage_1, vect_partial_vectors_usage_2,
vect_partial_vectors): Document.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/bb-slp-pr69907.c: Adjust for partial vector usages.

function.
