[X86] Add test case for LEA formation regression seen with D60358. NFC
If we have an (add X, (and (aext (shl Y, C1)), C2)), we can pull the shift through and+aext to fold into an LEA with the.
Assuming C1 is small enough and C2 masks off all of the extend bits.
This pattern showed up in D60358. And we need to handle it to prevent a regression.
