Rearrange the test cases of cond_widen_complicate-3 by different types
into different files, instead of put all types together.  Then we can
easily reduce the range when asm check fails.

The below test suites are passed locally, let's wait online CI says.
* The rv64gcv fully regression test.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3.c: Removed.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-f16.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-f32.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-i16.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-i32.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-i8.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-u16.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-u32.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3-u8.c: New test.
	* gcc.target/riscv/rvv/autovec/cond/cond_widen_complicate-3.h: New test.

I'm not opposed to refactoring but what's the reason for it?  We have a large 
number of similar tests that also include all possible types.  And aren't all 
the tests you touch FAILing anyway right now?  (Due to the combine change...)

Yes, the cond_widen_complicate-3 need some tweak for the asm check failure.
Simply adjust the count cannot guarantee that each type has generated at least
one vw/vfw. For example, i8 doesn't generate vw but i16 generate 2 vw insn,
and the final asm check times is the same.

Thus, I refactor them into different types to meet current behavior.

OK.

Not that I see it as absolute necessity but I don't mind either way.
We don't just want to tweak the asm checks, though.  The code is indeed
worse than before.

Thanks Robin.

I see, will leave other similar cases like cond_widen_complicate-[4|8] as is.
And it seems no other failures from rvv.exp now.
