The following pulls the trigger, defaulting --param vect-force-slp to 1.
I know of no features missing but eventually minor testsuite and
optimization quality fallout.
Bootstrapped and tested on x86_64-unknown-linux-gnu. I'll amend
PR116578 with the list of FAILs this causes (my baseline is outdated,
need to reproduce it).
* params.opt (vect-force-slp): Default to 1.
