Jakob Stoklund Olesen bf91c4e85e Analyze blocks with uses separately from live-through blocks without uses. 
About 90% of the relevant blocks are live-through without uses, and the only
information required about them is their number. This saves memory and enables
later optimizations that need to look at only the use-blocks.

Johnny Chen 0ec0e98a6a Add a missing opcode (SMLSLDX) to BadRegsMulFrm() function. 
Add more complete sanity check for LdStFrm instructions where if IBit (Inst{25})
is 1, Inst{4} should be 0.  Otherwise, we should reject the insn as invalid.

Jim Grosbach 23de2437bd RuntimeDyld should use the memory manager API. 
Start teaching the runtime Dyld interface to use the memory manager API
for allocating space. Rather than mapping directly into the MachO object,
we extract the payload for each object and copy it into a dedicated buffer
allocated via the memory manager. For now, just do Segment64, so this works
on x86_64, but not yet on ARM.

Qd -> bit[12] == 0

Johnny Chen 25883487a1 ARM disassembler was erroneously accepting an invalid LSL instruction. 
For register-controlled shifts, we should check that the encoding constraint
Inst{7} = 0 and Inst{4} = 1 is satisfied.

Chandler Carruth 78c7e34485 Commit a bit of a hack to fully handle the situation where variables are 
marked explicitly as uninitialized through direct self initialization:

  int x = x;

With r128894 we prevented warnings about this code, and this patch
teaches the analysis engine to continue analyzing subsequent uses of
'x'. This should wrap up PR9624.

There is still an open question of whether we should suppress the
maybe-uninitialized warnings resulting from variables initialized in
this fashion. The definitely-uninitialized uses should always be warned.
