Param for controlling FFR code generation.
Adds this to relevant tests that would otherwise break.
gcc/ChangeLog:
* params.opt (-param=vect-ffr-usage): New param
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/sve/noeffect11.c: Add --param=vect-ffr-usage=0
* gcc.target/aarch64/sve/peel_ind_12.c: Ditto.
* gcc.target/aarch64/sve/peel_ind_12_run.c: Ditto.
