The rvv_zvl*_ok checks use the same check_runtime property despite
testing different vector lengths. Whichever check runs first supplies
the cached result for all of them. Thus a VLEN=128 check can control
VLEN=256 tests and vice versa, causing unsupported tests to run or
supported tests to be skipped.
Give each check a unique property. The existing tests already cover
the affected checks and expose this order-dependent intermittent
failure, so no new testcase is needed.
gcc/testsuite/ChangeLog:
* lib/target-supports.exp (check_effective_target_rvv_zvl128b_ok):
Use a unique check_runtime property name.
(check_effective_target_rvv_zvl256b_ok): Likewise.
(check_effective_target_rvv_zvl_ge_256b_ok): Likewise.
(check_effective_target_rvv_zvl512b_ok): Likewise.
