[llvm-bugs] [Bug 235262] [clang] [DAGCombiner] visitVSELECT folds `x > C-1 ? x + -C : 0` to `usubsat x, C` also for lanes with C = 0, where the compare is the never-true `x > UINT_MAX`: those lanes return x instead of 0

Previous message: [llvm-bugs] [Bug 235261] [clang] [Mips] lowerShiftRightParts/lowerShiftLeftParts select on `and shamt, 32` (0 or 32, not a 0/1 boolean): `0x1FFFFFFFF >> (b & 32)` gives 0x2100000001 on MIPS32
Next message: [llvm-bugs] [Bug 235263] [clang][DAGCombiner] foldSelectToABD negates an INT_MIN constant lane: `|a + INT_MIN|` becomes `a + 2^31`
