Fix aot rotl/rotr 0 issue (#1285)

Fix the issue reported in #1282.
When i32/i64 rotate (rotl/rotr) with 0, the LLVM IRs translated are:
left<<0 | left>>64 and left >>0 | left<<64
The value of left >> 64 and left <<64 in LLVM are treated as poison,
which causes invalid result when executing the aot function.

Directly return left when right is 0 to fix the issue.
