[MLIR][LLVM] Incorrect #llvm.constant_range parse

[Kuree]

See godbolt: https://godbolt.org/z/x34YarsrE

range(i32 0, -2147483648) is imported as #llvm.constant_range<i32, 0, -2147483648>, but -2147483648 is internally stored as a 40-bit integer, causing the verifier to fail:

llvm-project/mlir/lib/Dialect/LLVMIR/IR/LLVMAttrs.cpp

Lines 290 to 293 in ebef440

	if (lower.getBitWidth() != upper.getBitWidth())
	return emitError()
	<< "expected lower and upper to have matching bitwidths but got "
	<< lower.getBitWidth() << " vs. " << upper.getBitWidth();
