[v2] RISC-V: Add test cases for the RVV mask insn shortcut.

  From: Pan Li <pan2.li@intel.com>

There are sorts of shortcut codegen for the RVV mask insn. For
example.

vmxor vd, va, va => vmclr vd.

We would like to add more optimization like this but first of all
we must add the tests for the existing shortcut optimization, to
ensure we don't break existing optimization from underlying shortcut
optimization.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/base/mask_insn_shortcut.c: New test.

LGTM. Wait for Kito more comments.

You're very welcome!

Looks vmorn(v,v) doesn't perform any shortcut, while vmandn(v, v) will be converted to vmclr in upstream. As I understand, there should be no difference between vmORn and vmANDn excepts the operator, will take a look from RTL CSE for more details, 😊!

BTW, this patch will be in GCC 13 or master? The underlying patches may depend on this tests for ensuring correctness.

You're very welcome!

Looks vmorn(v,v) doesn't perform any shortcut, while vmandn(v, v) will be converted to vmclr in upstream. As I understand, there should be no difference between vmORn and vmANDn excepts the operator, will take a look from RTL CSE for more details, 😊!
