[pan2 . li]

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

Add test cases for vsext.vf8 register group overlap, please
note it is not overlap as much as possible.

gcc/testsuite/ChangeLog:

        * gcc.target/riscv/rvv/autovec/group_overlap/vsext_vf8-i8-m1.c: New 
test.
        * gcc.target/riscv/rvv/autovec/group_overlap/vsext_vf8-i8-mf2.c: New 
test.
        * gcc.target/riscv/rvv/autovec/group_overlap/vsext_vf8-i8-mf4.c: New 
test.
        * gcc.target/riscv/rvv/autovec/group_overlap/vsext_vf8-i8-mf8.c: New
