RISC-V: Bugfix for RVV rounding intrinsic ICE in function checker

When compiling an interface for rounding of type 'vfloat16*' without using zvfh
or zvfhmin, it is not enough to use FLOAT_MODE_P because the type does not
support it. Although the subsequent riscv_validate_vector_type checks will
still fail and throw exceptions, I don't think we should have ICE here.

gcc/ChangeLog:

	* config/riscv/riscv-protos.h (riscv_vector_float_type_p): New.
	* config/riscv/riscv-vector-builtins.cc (function_instance::any_type_float_p):
	Use riscv_vector_float_type_p instead of FLOAT_MODE_P for judgment.
	* config/riscv/riscv.cc (riscv_vector_int_type_p): Change static to extern.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/base/bug-9.c: New test.
