RISC-V: Add test for FP llfloor auto vectorization
The below FP API are supported already by sharing the same standard name, as well as the machine mode. long long llfloor (double); This patch would like to add the test cases for ensuring the correctness. gcc/testsuite/ChangeLog: * gcc.target/riscv/rvv/autovec/unop/math-llfloor-0.c: New test. * gcc.target/riscv/rvv/autovec/unop/math-llfloor-run-0.c: New test. * gcc.target/riscv/rvv/autovec/vls/math-llfloor-0.c: New test.
