Ted Kremenek 121ddd6a5c Add another test case for PR 8015, here with the array index being within a valid range and not just a single constant.

Dan Gohman faa30f531a Reword this comment. Don't mention outs(), as that's not what 
this code is actually testing for.

Ted Kremenek 0e12f9cc7b Partial fix for PR 8015 (fix is actually by Jordy Rose, and I added a test case for follow-on work). This patch adds a bandaid for RegionStore's limited reasoning about symbolic array values.

Bob Wilson 1b87c9a646 Translate NEON vmull, vmlal, and vmlsl builtins to llvm multiply-add/sub 
with zext/sext operations, instead of to llvm intrinsics.  I have a plan to
avoid the clang builtins for these, but it is going to take a little longer
and I want to get the NEON intrinsics updated before the 2.8 release.

Jim Grosbach 63a8eaf559 Tweak to ignoring reserved regs. The allocator was occasionally still looking 
at them since they'd end up in the register weights list. Tell it to stop
doing that.

Dale Johannesen 092d3467bc Recommit with changes. Comment out palignr for the 
moment, as there's a testcase that uses it and expects it
to be subject to optimizations; we won't be doing that.
Some adjustments based on feedback from Bill.

Bruno Cardoso Lopes fea81b4831 Using target specific nodes for shuffle nodes makes the mask 
check more strict, breaking some cases not checked in the
testsuite, but also exposes some foldings not done before,
as this example:

  movaps  (%rdi), %xmm0
  movaps  (%rax), %xmm1
  movaps  %xmm0, %xmm2
  movss %xmm1, %xmm2
  shufps  $36, %xmm2, %xmm0

now is generated as:

  movaps  (%rdi), %xmm0
  movaps  %xmm0, %xmm1
  movlps  (%rax), %xmm1
  shufps  $36, %xmm1, %xmm0

Jakob Stoklund Olesen 4b6fd48bba Teach RemoveCopyByCommutingDef to check all aliases, not just subregisters. 
This caused a miscompilation in WebKit where %RAX had conflicting defs when
RemoveCopyByCommutingDef was commuting a %EAX use.

infinite loops or exits will eventually exit. This fixes PR5373.

physical register in a register class. Make sure to assert if the register
class is empty.

Jim Ingham 91b9383b76 Stream::Printf doesn't add a newline, so it needs to be added to all the error messages in CommandObjectExpression::EvaluateExpression.

Douglas Gregor a9aa29cf0b Implement libclang support for using declarations. Clang actually uses 
three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.

Several related changes here:
  - Cursor visitation of the three AST nodes for using declarations
  - Proper source-range computation for these AST nodes
  - Using declarations have no USRs, since they don't actually declare
    any entities.

Douglas Gregor 9dc243c3eb Improve libclang indexing support for class template specializations 
in a few related ways:

  - Don't recurse into instantiations of templates.
  - Recurse into explicit specializations.
  - Visit the template arguments of an explicit specialization or
    explicit instantiation.
  - Include template specialization arguments in the USRs for class
    template specializations.
