[PATCH] RISC-V: Add ZVFHMIN autovec block testcase

[PATCH] RISC-V: Add ZVFHMIN autovec block testcase

[juzhe.zhong]

From: Juzhe-Zhong <juzhe.zhong@rivai.ai>

To be safe, add ZVFHMIN autovec block testcase to make sure
we won't enable autovec in ZVFHMIN by mistakes.

gcc/testsuite/ChangeLog:

        * gcc.target/riscv/rvv/autovec/zvfhmin-1.c: New test.

Hi Juzhe,

no complaints here.  Just please make sure you add the commit
message or something related as top comment to the test when
committing.
Somebody who reads the test is not going to want to lookup
the commit message to know what's going on.

Regards
 Robin
