Hello Segher:
Here is the patch that uses xxlor instead of fmr where possible.
Performance results shows that fmr is better in power9 and
power10 architectures whereas xxlor is better in power7 and
power 8 architectures. fmr is the only option before p7.
Incorporated review comments.

This patch is the middle-end piece of an improvement to PRs 101955 and

The following ups the limit in fold_view_convert_expr to handle

The following fixes a mistake in count_nonzero_bytes which happily

The following fixes fallout of r10-7145-g1dc00a8ec9aeba which made
