0e72d5c3e5 Define __builtin_ffs[ll] with a signed argument instead of unsigned. 
GCC documents these as unsigned, but defines them as signed.

2da9d6d6cf [ms-inline asm] Instantiate the MCStreamer as a NullStream. We're parsing 
instruction, not emitting them, so a NullStream is fine.

714f595c98 Use standard pattern for iterate+erase. 
Increment the MBB iterator at the top of the loop to properly handle the
current (and previous) instructions getting erased.

This fixes PR13625.

I really need to find a way to automate this, but I can't come up with a regex
that has no false positives while handling tricky cases like custom check
prefixes.

Initializing a reference with itself, e.g. "int &a = a;" seems like a

5d944dbf1a Don't do jump-scope checking when code completion is enabled. It's 
both a waste of time, and prone to crash due to the use of the
error-recovery path in parser. Fixes <rdar://problem/12103608>, which
has been driving me nuts.

122a3a8e6f Fix undefined behavior in debug info emission: operator* on WeakVH returns a 
reference, so &* on an empty WeakVH binds a reference to a dereferenced null
pointer. So don't do that; we have a perfectly good implicit conversion to
Value*.

0564c75e7b [analyzer] Add an internal reference document describing IPA and CallEvent. 
This attempts to be a higher-level description of our inlining heuristics
and decision trees than the source, where the work is spread out between
ExprEngine (mostly in ExprEngineCallAndReturn.cpp) and CallEvent, with a
few other classes participating as well.

80b3c5a00e Don't form a null reference when checking for validity of an anonymous 
elaborated type specifier in template instantiation: such a specifier is always
valid because it must be specified within the definition of the type.

e4a5a90e8d Add support for "type safety" attributes that allow checking that 'void *' 
function arguments and arguments for variadic functions are of a particular
type which is determined by some other argument to the same function call.

Usecases include:
* MPI library implementations, where these attributes enable checking that
  buffer type matches the passed MPI_Datatype;
* for HDF5 library there is a similar usecase as MPI;
* checking types of variadic functions' arguments for functions like
  fcntl() and ioctl().

0ea1fce6b4 Add ADD and SUB to the predicable ARM instructions. 
It is not my plan to duplicate the entire ARM instruction set with
predicated versions. We need a way of representing predicated
instructions in SSA form without requiring a separate opcode.

Then the pseudo-instructions can go away.

2382d320b3 Add an MCID::Select flag and TII hooks for optimizing selects. 
Select instructions pick one of two virtual registers based on a
condition, like x86 cmov. On targets like ARM that support predication,
selects can sometimes be eliminated by predicating the instruction
defining one of the operands.

Teach PeepholeOptimizer to recognize select instructions, and ask the
target to optimize them.
