Add an initial implementation of PHI translation for LazyValueInfo.  This involves rolling back some
of my earlier data structure improvements until I can ensure that there are no iterator invalidation problems.

Add -disable-shifter-op to disable isel of shifter ops. On Cortex-a9 the shifts cost extra instructions so it might be better to emit them separately to take advantage of dual-issues.

launch it due to not being able to get the task port. A SIGHUP was killing us
and also an error string wasn't properly being passed along. Got rid of a
class error variable that can only lead to multi-threaded crashes.

later to identify and possibly remove superfluous compare instructions -- those

Change the prototype of ScriptInterpreter::ExecuteOneLine() to return bool
instead of void and take one additional parameter as CommandReturnObject *.

Propagate the status of one-liner execution back appropriately.

formerly rejected by the FE, so asserted in the BE; now the FE only
warns, so we treat it as a legitimate fatal error in PPC BE.
This means the test for the feature won't pass, so it's xfail'd.

Added "void Clear();" methods to SBDebugger, SBTarget and SBThread so they can release their shared pointers.

declared during the addition of the assembler support, the additional
changes are:
- Add missing intrinsics
- Move all SSE conversion instructions in X86InstInfo64.td to the SSE.td file.
- Duplicate some patterns to AVX mode.
- Step into PCMPEST/PCMPIST custom inserter and add AVX versions.

This patch introduces the ClassTemplateDecl::spec_{begin,end}()
and FunctionTemplateDecl::{,partial_}spec_{begin,end}() member
functions as a public interface for iterating over the declarations'
specialisation sets.

llvm-svn: 109870

This patch reimplements the find*Specialization family of member
functions of {Class,Function}TemplateDecl in terms of a common
implementation that uses SpecEntryTraits to obtain the most recent
declaration.

SpecEntryTraits describes how to obtain the most recent declaration
of a specialisation from an entry in a specialisation FoldingSet.

When we are deserializing the lexical decls of a DeclContext from PCH, notify the PCHReader to hold off passing Decls
to the consumer until the DeclContext is fully prepared.

Before, due to recursive loading, we could be in a situation where we would try to deserialize the decls of a DeclContext which was already doing that, and bad things would happen. In the specific case I encountered, the lexical decls would
form a cycle and we would enter infinite loop territory.

-Replace CurrentlyLoadingTypeOrDecl with a counting scheme (NumCurrentElementsDeserializing)
-Provide outside access to the mechanism by adding methods StartedDeserializing/FinishedDeserializing
  to ExternalASTSource.

These are preparation for the next commit.
