5d618ef7f1 Switch llvm to using comdats. For now always use groups with a single 
section.

b13bafe5c1 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.

42bf74be14 CodeGen still defaults to non-verbose asm, but llc now overrides it and default to verbose.

be3bf42331 Fix a x86-64 codegen deficiency. Allow gv + offset when using rip addressing mode. 
Before:
_main:
        subq    $8, %rsp
        leaq    _X(%rip), %rax
        movsd   8(%rax), %xmm1
        movss   _X(%rip), %xmm0
        call    _t
        xorl    %ecx, %ecx
        movl    %ecx, %eax
        addq    $8, %rsp
        ret
Now:
_main:
        subq    $8, %rsp
        movsd   _X+8(%rip), %xmm1
        movss   _X(%rip), %xmm0
        call    _t
        xorl    %ecx, %ecx
        movl    %ecx, %eax
        addq    $8, %rsp
        ret

Notice there is another idiotic codegen issue that needs to be fixed asap:
xorl    %ecx, %ecx
movl    %ecx, %eax

460b8bd154 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.
