f9365363db Remove context sensitivity concerns from interprocedural-basic-aa, and 
make it more aggressive in cases where both pointers are known to live
in the same function.

a0fa700f3c Debugging infomration is encoded in llvm IR using metadata. This is designed 
such a way that debug info for symbols preserved even if symbols are
optimized away by the optimizer. 

Add new special pass to remove debug info for such symbols.

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%.

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.
