Support left and right shift operators in JIT (#34563)
Summary:
With this PR, we can now support left and right shift operators in the JIT engine for <int, int> and <Tensor, int>.
Updated tests pass as expected:
```
> python test/test_jit.py
...
Ran 2427 tests in 84.861s
OK (skipped=139, expected failures=1)
```
Running the following code with Python results in the output below:
```
> cat ~/expressions.py
import torch
torch.jit.script
def fn(a, b):
# type: (int, int)
return (
a << b, # supported
b >> a, # supported
a & b,
a | b,
a ^ b
)
print(fn.graph)
```
```
> python ~/expressions.py
graph(%a.1 : int,
%b.1 : int):
%4 : int = aten::leftshift(%a.1, %b.1) # /home/ince/expressions.py:7:8
%7 : int = aten::rightshift(%b.1, %a.1) # /home/ince/expressions.py:8:8
%10 : int = aten::__and__(%a.1, %b.1) # /home/ince/expressions.py:9:8
%13 : int = aten::__or__(%a.1, %b.1) # /home/ince/expressions.py:10:8
%16 : int = aten::__xor__(%a.1, %b.1) # /home/ince/expressions.py:11:8
%17 : (int, int, int, int, int) = prim::TupleConstruct(%4, %7, %10, %13, %16)
return (%17)
