XThreadVector does not support the vsext/vzext instructions; however,
due to the reuse of RVV optimizations, it may generate these instructions

we should disable these patterns.
gcc/ChangeLog:
* config/riscv/vector.md: Disable vsext/vzext for XTheadVector.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/xtheadvector/vsext.c: New test.

Mostly OK. The only change we might need is removal of the
"-save-temps" option in the testcase. I don't think that should be
necessary, we certainly don't need it with other scan-asm tests.
OK with the -save-temps removed.
