3e883734fa During the CodeGenPrepare we often lower intrinsics (such as objsize) 
and allow some optimizations to turn conditional branches into unconditional.
This commit adds a simple control-flow optimization which merges two consecutive
basic blocks which are connected by a single edge. This allows the codegen to
operate on larger basic blocks.

7b6783a03f LICM uses AliasSet information to hoist and sink instructions. However, other passes, such as LoopRotate 
may invalidate its AliasSet because SSAUpdater does not update the AliasSet properly.
This patch teaches SSAUpdater to notify AliasSet that it made changes.
The testcase in PR12901 is too big to be useful and I could not reduce it to a normal size.

8dff60e96a MemoryDependenceAnalysis attempts to find the first memory dependency for function calls. 
Currently, if GetLocation reports that it did not find a valid pointer (this is the case for volatile load/stores),
we ignore the result. This patch adds code to handle the cases where we did not obtain a valid pointer.

6d2986cd03 ARM: Move Thumb2 tests to Thumb2 test file and fix CHECK lines. 
These tests weren't actually being run before (missing ':' after CHECK).

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161800 91177308-0d34-0410-b5e6-96231b3b80d8

43600e95ec Remove the TII::scheduleTwoAddrSource() hook. 
It never does anything when running 'make check', and it get's in the
way of updating live intervals in 2-addr.

The hook was originally added to help form IT blocks in Thumb2 code
before register allocation, but the pass ordering has changed since
then, and we run if-conversion after register allocation now.

When the MI scheduler is enabled, there will be no less than two
schedulers between 2-addr and Thumb2ITBlockPass, so this hook is
unlikely to help anything.
