Hi Jin Ma,
Precommit has flagged a large number of ICEs with this patch on vector
targets when applied to yesterday's daily bump[1]:

Thanks,

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.
