729eb14ae8 Various updates from Sam Bishop: 
"I have been working my way through the JIT and Kaleidoscope tutorials in my
(minuscule) spare time.  Thanks again for writing them!  I have attached a
patch containing some minor changes, ranging from spelling and grammar fixes
to adding a "Next: <next tutorial section>" hyperlink to the bottom of each
page.

Every page has been given the "next link" treatment, but otherwise I'm only
half way through the Kaleidoscope tutorial.  I will send a follow-on patch
if time permits."

9071dd3a57 check that terminators only occur at the end of a block. This catches the 
common problem of putting two terminators in the same block.  I can't write
a testcase for this because the .ll parser rejects this before the verifier
can, but this can occur when generating IR.

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
