8022d8e885 Teach fast-isel to avoid loading a value from memory when it's already
available in a register. This is pretty primitive, but it reduces the
number of instructions in common testcases by 4%.

c944ad6634 Don't use operator[] here, because it's not desirable to insert a default

956316a3d7 - Add AVX SSE2 Move doubleword and quadword instructions.
- Add encode bits for VEX_W
- All 128-bit SSE 1 & SSE2 instructions that are described
  in the .td file now have a AVX encoded form already working.

547c92af20 In ScalarEvolution::forgetValue, eliminate any SCEVUnknown
entries associated with the value being erased in the
folding set map.  These entries used to be harmless, because
a SCEVUnknown doesn't store any information about its Value*,
so having a new Value allocated at the old Value's address
wasn't a problem. But now that ScalarEvolution is storing more
information about values, this is no longer safe.

38c76cc88a Remember to track spill slot uses in VirtRegMap when inserting loads and stores.
LocalRewriter::runOnMachineFunction uses this information to mark dead spill
slots.

This means that InlineSpiller now also works for functions that spill.

de6d3111d0 Rather than giving SmallPtrSetImpl a member field SmallArray which is magically
replaced by a bigger array in SmallPtrSet (by overridding it), instead just use a
pointer to the start of the storage, and have SmallPtrSet pass in the value to use.
This has the disadvantage that SmallPtrSet becomes bigger by one pointer.  It has
the advantage that it no longer uses tricky C++ rules, and is clearly correct while
I'm not sure the previous version was.  This was inspired by g++-4.6 pointing out
that SmallPtrSetImpl was writing off the end of SmallArray, which it was.  Since
SmallArray is replaced with a bigger array in SmallPtrSet, the write was still to
valid memory.  But it was writing off the end of the declared array type - sounds
kind of dubious to me, like it sounded dubious to g++-4.6.  Maybe g++-4.6 is wrong
and this construct is perfectly valid and correctly compiled by all compilers, but
I think it is better to avoid the whole can of worms by avoiding this construct.
