RISC-V: Add autovect widening/narrowing Integer/FP conversions.
This patch implements widening and narrowing float-to-int and
int-to-float conversions and adds tests.
gcc/ChangeLog:
* config/riscv/autovec.md (<optab><vnconvert><mode>2): New
expander.
(<float_cvt><vnconvert><mode>2): Ditto.
(<optab><mode><vnconvert>2): Ditto.
(<float_cvt><mode><vnconvert>2): Ditto.
* config/riscv/vector-iterators.md: Add vnconvert.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/conversions/vfncvt-ftoi-run.c: New test.
