On Darwin, ams printer should output a second label before a jump table so the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body. llvm-svn: 73720

Verify that jump tables are emitted to the same section as the function is, when codegen'ing in pic mode. This fixes a miscompilation of a switch stmt in a template, as the template goes to a non-.text section. llvm-svn: 30743
