Venkatraman Govindaraju 3b71b0ae3d Fix SPARC backend call instruction so that arguments passed through registers 
are correctly marked as used instead of passing all possible argument registers
as used.

Greg Clayton 722a0cdc95 Added the following functions to SBThread to allow threads to be suspended when a process is resumed: 
bool SBThread::Suspend();
bool SBThread::Resume();
bool SBThread::IsSuspended();

Chris Lattner 654098f411 revert r123146 which disabled code that wasn't the root cause 
of the bootstrap miscompare issue.

the source of the bootstrap problem.

Jason W Kim 9c5b65d289 1. Support ELF pcrel relocations for movw/movt: 
R_ARM_MOVT_PREL and R_ARM_MOVW_PREL_NC.
2. Fix minor bug in ARMAsmPrinter - treat bitfield flag as a bitfield, not an enum.
3. Add support for 3 new elf section types (no-ops)

Douglas Gregor 74c6d19c1f Add TemplateArgument::CreatePackCopy() to create a new parameter pack 
in ASTContext-allocated memory, copying the provided template
arguments. Use this new routine where we can. No functionality change.

Jakob Stoklund Olesen f2407aa98b Fix a non-deterministic loop in llvm::MergeBlockIntoPredecessor. 
DT->changeImmediateDominator() trivially ignores identity updates, so there is
really no need for the uniqueing provided by SmallPtrSet.

I expect this to fix PR8954.

Douglas Gregor 2fcb863b2b Implement partial ordering of class template partial specializations 
and function templates that contain variadic templates. This involves
three small-ish changes:

  (1) When transforming a pack expansion, if the transformed argument
  still contains unexpanded parameter packs, build a pack
  expansion. This can happen during the substitution that occurs into
  class template partial specialiation template arguments during
  partial ordering. 
 
  (2) When performing template argument deduction where the argument
  is a pack expansion, match against the pattern of that pack
  expansion.

  (3) When performing template argument deduction against a non-pack
  parameter, or a non-expansion template argument, deduction fails if
  the argument itself is a pack expansion (C++0x
  [temp.deduct.type]p22).

Cameron Zwarich cb9c4f85ec Dial back the speculative fix for PR8954 a bit, so that we only recompute dominators 
once at the beginning of GVN instead of once per iteration.

Jakob Stoklund Olesen 803f48bcd1 Don't insert DBG_VALUE instructions after the first terminator. 
For one, MachineBasicBlock::getFirstTerminator() doesn't understand what is
happening, and it also makes sense to have all control flow run through the
DBG_VALUE.

Argyrios Kyrtzidis 4b7433fab2 [analyzer] Introduce ObjCSelfInitChecker, which checks initialization methods to verify that they assign 'self' to the 
result of an initialization call (e.g. [super init], or [self initWith..]) before using any instance variable or
returning 'self'.

Argyrios Kyrtzidis 52f04650ae [analyzer] Add 'bool ignorePrefix' parameter to cocoa::deriveNamingConvention to control whether 
the prefix should be ignored.

E.g. if ignorePrefix is true, "_init" and "init" selectors will both be result in InitRule, but if
ignorePrefix is false, only "init" will return InitRule.

Douglas Gregor b837ea4eee Implement C++ [temp.func.order]p5 more directly, by passing down the 
number of explicit call arguments. This actually fixes an erroneous
test for [temp.deduct.partial]p11, where we were considering
parameters corresponding to arguments beyond those that were
explicitly provided.

Daniel Dunbar 9d944b3fcc McARM: Add more hard coded logic to SplitMnemonicAndCC to also split out the 
carry setting flag from the mnemonic.

Note that this currently involves me disabling a number of working cases in
arm_instructions.s, this is a hopefully short term evil which will be rapidly
fixed (and greatly surpassed), assuming my current approach flies.

Jay Foad c8adf5f458 FixedNumOperandTraits and VariadicOperandTraits assumed that, given a 
"this" pointer for any subclass of User, you could static_cast it to
User* and then reinterpret_cast that to Use* to get the end of the
operand list. This isn't a safe assumption in general, because the
static_cast might adjust the "this" pointer. Fixed by having these
OperandTraits classes take an extra template parameter, which is the
subclass of User. This is groundwork for PR889.
