Greg Clayton c00ca313fd Fix a crasher that could happen when you run LLDB and evaluate an expression where the objective C runtime registers a helper function, and also have an Objective C or C++ exception breakpoint. When shutting down the process in Process::Finalize() we clear a STL collection class and that causes objects to be destroyed that could re-enter Process and cause it to try to iterate over that same collection class that is being destroyed.
Guard against this by setting a new "m_finalizing" flag that lets us know we are in the process of finalizing.

Chaoren Lin 4ced470a31 Fix issue where GPR and FPR registers have overlapping byte offsets.
Summary:
The implementation of GDBRemoteRegisterContext relies on byte offsets to cache
register values. GPR, FPR, etc. should start on different offsets. This is
correctly done in debugserver (in DNBArchImplX86_64.cpp), but not on Linux or
FreeBSD (in RegisterInfos_x86_64.h).

Test Plan: `register read st0` no longer overwrites `rbp` on Linux with LLGS.

Zachary Turner e6e2bb3842 Rework LLDB system initialization.
In an effort to reduce binary size for components not wishing to
link against all of LLDB, as well as a parallel effort to reduce
link dependencies on Python, this patch splits out the notion of
LLDB initialization into "full" and "common" initialization.

All code related to initializing the full LLDB suite lives directly
in API now.  Previously it was only referenced from API, but because
it was defined in lldbCore, it would get implicitly linked against
by everything including lldb-server, causing a considerable
increase in binary size.

By moving this to the API layer, it also creates a better layering
for the ongoing effort to make the embedded interpreter replacable
with one from a different language (or even be completely removeable).

One semantic change necessary to get this all working was to remove
the notion of a shared debugger refcount.  The debugger is either
initialized or uninitialized now, and calling Initialize() multiple
times will simply have no effect, while the first Terminate() will
now shut it down no matter how many times Initialize() was called.
This behaves nicely with all of our supported usage patterns though,
and allows us to fix a number of nasty hacks from before.

Siva Chandra 462722d135 [DWARF] Generate qualified names of functions if linkage names are missing.
Summary:
This is similar to the change introduced for variable DIEs in r233098. If the
linkage names of functions are missing in the DWARF, then their fully qualified
names (similar to the name that would be got by demangling their linkage name)
is generated using the decl context.

This change fixes TestNamespace when the test case is compiled with GCC, hence
it is enabled for GCC. The test and the test case are also enhanced to cover
variadic functions.

Zachary Turner e6d213a84a Fix a race condition in Target::Launch
When no hijack listener is set up, the global event listener will
try to pull events off the queue, racing with the event thread.
By always forcing a hijack listener, even when one was not given,
we guarantee that the listener always gets all events.

This was causing problems in synchronous mode with the process
stop event sometimes never being picked up and causing the debugger
to hang while processing a .lldbinit file.

Chaoren Lin f9e915ae10 ComputeSupportExeDirectory for Linux
Summary:
Fixes http://reviews.llvm.org/D8511

The original method of using dladdr() could return the incorrect relative
path if not dynamically linked against liblldb and the working directory
has changed. This is not a problem when built with python, since
ScriptInterpreterPython::InitializePrivate calls
HostInfo::GetLLDBPath(ePathTypeLLDBShlibDir, ...) and caches the
correct path before any changes to the working directory.

The /proc/self/exe approach fails if run using Python, but works for all other
cases (including for android, which doesn't have dladdr()).

So if we combine the two, we should reasonably cover all corner cases.

Zachary Turner a98fac28aa Fix error introduced by changing function signatures.
Since ClangASTSource::layoutRecordType() was overriding a virtual
function in the base, this was inadvertently causing a new method
to be introduced rather than an override.  To fix this all method
signatures are changed back to taking DenseMaps, and the `override`
keyword is added to make sure this type of error doesn't happen
again.

To keep the original fix intact, which is that fields and bases
must be added in offset order, the ImportOffsetMap() function
now copies the DenseMap into a vector and then sorts the vector
on the value type (e.g. the offset) before iterating over the
sorted vector and inserting the items.

Siva Chandra 0783ab9a7f [DWARF] If linkages names are missing, use decl context to get qualified names.
Summary:
This commit adds this alternate route only when parsing variable dies
corresponding to global or static variables. The motivation for this is that GCC
does not emit linkage names for functions and variables declared/defined in
anonymous namespaces. Having this alternate route fixes one part of
TestNamespace which fails when the test case is compiled with GCC.

An alternate route to get fully qualified names of functions whose linkage names
are missing will be added with a followup change. With that, the other failing
part of TestNamespace will also be fixed.

Zachary Turner 504f38da4e Fix record layout when synthesizing class types.
Prior to this patch, we would try to synthesize class types by
iterating over a DenseMap of FieldDecls and adding each one to
a CXXRecordDecl.  Since a DenseMap doesn't provide a deterministic
ordering of the elements, this would not add the fields in
FieldOffset order, but rather in some random order determined by
the memory layout of the DenseMap.

This patch fixes the issue by changing DenseMaps to vectors.  The
ability to lookup a value in the DenseMap was hardly being used,
and where it is sufficient to do a vector lookup.
