The test case gcc.dg/tree-ssa/copy-headers-8.c fails for a target where
LOGICAL_OP_NON_SHORT_CIRCUIT is defined as 0.It is suggested to add
`--param logical-op-non-short-circuit=1` to the test case to make it a
target-independent testcase.

Hi, Jiahao:
This patch will introduce redundant FAIL, and the reason needs to be explained.
+FAIL: gcc.dg/tree-ssa/copy-headers-8.c scan-tree-dump-times ch2 "Conditional
combines static and invariant" 1
+FAIL: gcc.dg/tree-ssa/copy-headers-8.c scan-tree-dump-times ch2 "Will duplicate
bb" 2
+FAI
Define LOGICAL_OP_NON_SHORT_CIRCUIT as 0, for a short-circuit branch, use the
short-circuit operation instead of the non-short-circuit operation.
SPEC2017 performance evaluation shows 1% performance improvement for fprate
GEOMEAN and no obvious regression for others. Especially, 526.blender_r +10.
