Jim Grosbach 7db8d697cf Thumb2 assembly parsing and encoding for LDRD(immediate). 
Refactor operand handling for STRD as well. Tests for that forthcoming.

Caitlin Sadowski ee5db8b5c4 Thread Safety: In C++0x Mutexes are the objects that control access to shared variables, while Locks are the objects that acquire and release Mutexes. We switch to this new terminology.

Bruno Cardoso Lopes 46b9cde019 Add a AVX version of a simple i64 -> f64 bitcast. This could be 
triggered using llc with -O0, which wouldn't let it be folded and
expose the lack of this pattern.

Jakob Stoklund Olesen ed2a360fd1 The frexp, modf, and remquo builtins are not 'const'. 
These functions return a second value by writing to a pointer argument,
so they cannot be marked 'readnone' which implies that they don't access
memory.

Bruno Cardoso Lopes 23eb5265b4 * Combines Alignment, AuxInfo, and TB_NOT_REVERSABLE flag into a 
single field (Flags), which is a bitwise OR of items from the TB_*
enum. This makes it easier to add new information in the future.

* Gives every static array an equivalent layout: { RegOp, MemOp, Flags }

* Adds a helper function, AddTableEntry, to avoid duplication of the
insertion code.

* Renames TB_NOT_REVERSABLE to TB_NO_REVERSE.

* Adds TB_NO_FORWARD, which is analogous to TB_NO_REVERSE, except that
it prevents addition of the Reg->Mem entry. (This is going to be used
by Native Client, in the next CL).

Bruno Cardoso Lopes fb113a0051 Add AVX versions of blend vector operations and fix some issues noticed 
in Nadav's r139285 and r139287 commits.

1) Rename vsel.ll to a more descriptive name
2) Change the order of BLEND operands to "Op1, Op2, Cond", this is
necessary because PBLENDVB is already used in different places with
this order, and it was being emitted in the wrong way for vselect
3) Add AVX patterns and tests for the same SSE41 instructions

Douglas Gregor bab8a96f2f Implement the Objective-C 'instancetype' type, which is an alias of 
'id' that can be used (only!) via a contextual keyword as the result
type of an Objective-C message send. 'instancetype' then gives the
method a related result type, which we have already been inferring for
a variety of methods (new, alloc, init, self, retain). Addresses
<rdar://problem/9267640>.

Johnny Chen af3d4af4eb Add logic to the DNBArchImplX86_64/DNBArchImplI386::NotifyException() callback method 
in order to distinguish the real single step exception from a watchpoint exception
which uses the same exc_type of EXC_BREAKPOINT and exc_code of EXC_I386_SGL.

This is done by checking the debug status register to find out whether the watchpoint
data break event has fired, and, if yes, stuff the data break address into the exception's
exc_sub_code field on the debugserver side for lldb to consume on the other end.
