Sean Callanan 4538aa25bd Fixed a crasher that occurs when an expression
doesn't return a result.  If that expression can't
be run in the current context (for example, if it
uses a function and there is no running process)
then we used to try to destroy the nonexistent
result variable.  We now only destroy the result
variable if we actually made one.

Enrico Granata b046e0320c This patch fixes a bug where LLDB was incorrectly setting the address-size on a DataExtractor to be sizeof(void*) when the ValueObject came out of the expression parser
This worked correctly for 64-bit targets, but broke down data formatters in i386 mode. The formatters would try to read pointers out of the frozen-dried objects,
but were unable to do so because they would try fetching 8 bytes from a DataExtractor with only 4 bytes in it. This patch fixes the issue by always making the pointer-size
for a DataExtractor match the target setting.

Greg Clayton 2dafd8ed4b <rdar://problem/11282938>
Fixed an issue where we get NULL compile units back from the symbol vendor. We need symbol vendors to be able to quickly give an estimate of the compile units that they have without having to fully vette them first, so anyone getting compile units from a module should be able to deal with a NULL compile unit being returned for a given index.

Jim Ingham 6d66ce67d7 Make sure the "synchronous breakpoint callbacks" get called before the thread plan logic gets invoked, and if they
ask to continue that should short-circuit the thread plans for that thread.  Also add a bit more explanation for
how this machinery is supposed to work.  
Also pass eExecutionPolicyOnlyWhenNeeded, not eExecutionPolicyAlways when evaluating the expression for breakpoint
conditions.

Greg Clayton 9bbddbf84a Added logging so we can see when we are trying to complete a forward type and pull in the world. This is due to a compiler bug we are tracking (<rdar://problem/11291658>) where forward decls to classes and types are not properly scoped in namespaces, which results in the current LLDB looking for a type it will find many times in the accelerator tables, but never match. For example, when debugging with clang we get a forward decl like:
class AnalysisResolver;

And we will look for it everywhere and find many many matches, but the decl context of those matching DIEs is "clang::AnalysisResolver", so we never match anything, yet we pull in waaayyy too much DWARF in the process.

To enable this logging enable the "lookups" category in the "dwarf" log channel:

(lldb) log enable dwarf lookups

Greg Clayton d1cf11a74d Added a new host function that allows us to run shell command and get the output from them along with the status and signal:
Error
Host::RunShellCommand (const char *command,
                       const char *working_dir,
                       int *status_ptr,
                       int *signo_ptr,

                       uint32_t timeout_sec);

This will allow us to use this functionality in the host lldb_private::Platform, and also use it in our lldb-platform binary. It leverages the existing code in Host::LaunchProcess and ProcessLaunchInfo.
