RISC-V: Expand vec abs without masking.
Standard abs synthesis during expand is max (a, -a). This
expansion has the advantage of avoiding masking and is thus potentially
faster than the a < 0 ? -a : a synthesis.
gcc/ChangeLog:
* config/riscv/autovec.md (abs<mode>2): Expand via max (a, -a).
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/unop/abs-rv32gcv.c: Adjust test
expectation.
