Determine whether a spill kills the register it's spilling before insertion rather than trying to undo the kill marker afterwards.

maybe c380004 can be hyperlinked too?

"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."

This fixes the store case, my previous patch just fixed the load
case.  rdar://5707076.

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.

begin adding some methods to use it this way.

It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned.

128-bit vectors need it only when SSE is on.
