RISC-V: Add autovec FP int->float conversion.

This patch adds the autovec expander for vfcvt.f.x.v and tests for it.

gcc/ChangeLog:

	* config/riscv/autovec.md (<float_cvt><vconvert><mode>2): New
	expander.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/conversions/vfcvt_rtz-run.c: Adjust.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt_rtz-rv32gcv.c:
	Ditto.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt_rtz-rv64gcv.c:
	Ditto.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt_rtz-template.h:
	Ditto.
	* gcc.target/riscv/rvv/autovec/conversions/vncvt-template.h:
	Ditto.
	* gcc.target/riscv/rvv/autovec/conversions/vsext-template.h:
	Ditto.
	* gcc.target/riscv/rvv/autovec/conversions/vzext-template.h:
	Ditto.
	* gcc.target/riscv/rvv/autovec/zvfhmin-1.c: Add int/float conversions.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt-itof-run.c: New test.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt-itof-rv32gcv.c: New test.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt-itof-rv64gcv.c: New test.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt-itof-template.h: New test.
	* gcc.target/riscv/rvv/autovec/conversions/vfcvt-itof-zvfh-run.c: New test.
