that check pointer validity fail to parse. Now
lldb does not crash in that case. Also added
support for checking Objective-C class validity
in the Version 1 runtime as well as Version 2
runtimes with varying levels of available debug
support.

sequence of loads and stores was being generated to perform the
copy on the x86 targets if the parameter was less than 4 byte
aligned, causing llc to use up vast amounts of memory and time.
Use a "rep movs" form instead. PR7170.

To create debugging information for a pointer, using DIBUilder front-end just needs
DBuilder.CreatePointerType(Ty, Size);
instead of
DebugFactory.CreateDerivedType(llvm::dwarf::DW_TAG_pointer_type,
TheCU, "", getOrCreateMainFile(),
0, Size, 0, 0, 0, OCTy);

fixed them. Added DISALLOW_COPY_AND_ASSIGN to classes that should
not be bitwise copied. Added default initializers for member
variables that weren't being initialized in the ctor. Fixed a few
shadowed local variable mistakes.

e.g. for:
template <int i> class A {
class B *g;
};
'class B' has the template as lexical context but semantically it is
introduced in namespace scope.

Right now the code is partitioned but the behavior is the same.
This should be improved in the near future. This removes some
uses of TheOperandList.

adding support into lldb_private::Process:
virtual uint32_t
lldb_private::Process::LoadImage (const FileSpec &image_spec,
Error &error);
virtual Error
lldb_private::Process::UnloadImage (uint32_t image_token);
There is a default implementation that should work for both linux and MacOSX.
This ability has also been exported through the SBProcess API:
uint32_t
lldb::SBProcess::LoadImage (lldb::SBFileSpec &image_spec,
lldb::SBError &error);
lldb::SBError
lldb::SBProcess::UnloadImage (uint32_t image_token);
Modified the DynamicLoader plug-in interface to require it to be able to
tell us if it is currently possible to load/unload a shared library:
virtual lldb_private::Error
DynamicLoader::CanLoadImage () = 0;
This way the dynamic loader plug-ins are allows to veto whether we can
currently load a shared library since the dynamic loader might know if it is
currenlty loading/unloading shared libraries. It might also know about the
current host system and know where to check to make sure runtime or malloc
locks are currently being held.
Modified the expression parser to have ClangUserExpression::Evaluate() be
the one that causes the dynamic checkers to be loaded instead of other code
that shouldn't have to worry about it.

RegisterContextLLDB holds a reference to the SymbolContext
in the vector of Cursors that UnwindLLDB maintains. Switch
UnwindLLDB to hold a vector of shared pointers of Cursors
so this reference doesn't become invalid.
Correctly falling back from the "fast" UnwindPlan to the
"full" UnwindPlan when additional registers need to be
retrieved.

now matchables contain an explicit list of how to populate each
operand in the result instruction instead of having them somehow
magically be correlated to the input inst.

This way, InlineSpiller does the same amount of splitting as the standard
spiller. Splitting should really be guided by the register allocator, and
doesn't belong in the spiller at all.
