Merge commit 37b7207651b4 from llvm-project (by zhongyunde@huawei.com):
[SimplifyCFG] Fix crash when there is unreachable large index (#88616) The large case index out of scope is dead code, but it is still be created for TableContents in SwitchLookupTable::SwitchLookupTable, so make sure the table size after growing should not get smaller. Fix https://github.com/llvm/llvm-project/issues/88607
This should fix "Assertion failed: (idx < size()), function operator[]"
when building the science/dynare port.
