Fix codegen bug in PIC version of genSwitch (#12433)
Summary:
* getNonClobberedReg instead of getSomeReg, because the reg needs to
survive across t_code
* Use a new reg for the table offset calculation instead of clobbering
the reg returned by expr (this was the bug affecting #12433)
Test Plan: New unit test; validate
