e15c6c11b4 Add an empty key for DebugLoc so that you can store an empty DebugLoc in a 
DenseMap.

bb79ab5ba3 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.

765dec3867 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.

8a1f712b53 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

6e1367d5dd ARM disassembler was erroneously accepting an invalid LSL instruction.

Inst{7} = 0 and Inst{4} = 1 is satisfied.

7e2e555075 Added *hidden* flags -print-options and -print-all-options so 
developers can see if their driver changed any cl::Option's. The
current implementation isn't perfect but handles most kinds of
options. This is nice to have when decomposing the stages of
compilation and moving between different drivers. It's also a good
sanity check when comparing results produced by different command line
invocations that are expected to produce the comparable results.

Note: This is not an attempt to prolong the life of cl::Option. On the
contrary, it's a placeholder for a feature that must exist when
cl::Option is replaced by a more appropriate framework. A new
framework needs: a central option registry, dynamic name lookup,
non-global containers of option values (e.g. per-module,
per-function), *and* the ability to print options values and their defaults at
any point during compilation.
