New Revision: 242312

URL: https://gcc.gnu.org/viewcvs?rev=242312&root=gcc&view=rev
Log:
Add optabs for common types of permutation

...so that we can use them even with variable-length vectors.
The vector optabs are inconsistent about whether there should be
an underscore before the mode part of the name, but the other hi/lo
optabs have one.
