llvm.memcpy.* has two distinct associated address spaces; the source address space, and the destination address space. Fix up the interface on MemIntrinsic and MemTransferInst to make this clear, and fix InstructionDereferencesPointer in LazyValueInfo.cpp to use the interface properly.

Teach LazyValueInfo that allocas aren't NULL. Over all of llvm-test, this saves
half a million non-local queries, each of which would otherwise have triggered a
linear scan over a basic block.
Also fix a fixme for memory intrinsics which dereference pointers. With this,
we prove that a pointer is non-null because it was dereferenced by an intrinsic
112 times in llvm-test.

* mergeIn now uses constant folding for constants that are provably not-equal.
* sink some sanity checks from the get*() methods into the mark*() methods, to ensure that we never have a constant/notconstant ConstantInt
* some textual cleanups, whitespace changes, removing "else" after return, that sort of thing.

It is possible, under specific circumstances involving ptrtoint ConstantExpr's, for LVI to end up trying to merge
a Constant into a ConstantRange. Handle this conservatively for now, rather than asserting. The testcase is
more complex that I would like, but the manifestation of the problem is sensitive to iteration orders and the state of the
LVI cache, and I have not been able to reproduce it with manually constructed or simplified cases.
Fixes PR8162.

It is possible to try to merge a not-constant with a constantrage, when dealing with ptrtoint ConstantExpr's.

sensitive to iteration-order issues, since the problem only occurs when merging values in a particular order.

Revert my last two patches to LVI, which recent changes have exposed a miscompilation in.

Pass the queried value by argument rather than in a member, in preparation for supporting PHI translation.

Get rid of LVIQuery as a distinct data structure, so that we don't have to initialize a new set of maps on every query.

Rearrange several datastructures in LazyValueInfo to improve compile time.
This is still not perfect, but better than it was before.

teach LVI to infer edge information from switch instructions.
This allows JT to eliminate a ton of infeasible edges when
handling code like the templates in PatternMatch.h

implement the first stab at caching queries. This isn't correct
(because the invalidation logic is missing) but LVI isn't enabled
by default anyway.

constant constraints. Improve the LVI lattice to include inequality
constraints.

strswitch.

stub out some LazyValueInfo interfaces, and have JumpThreading
start using them in a trivial way when -enable-jump-threading-lvi
is passed. enable-jump-threading-lvi will be my playground for
awhile.
