SUMMARY
Flakey tests get two chances to pass
Also, switched a bunch of tests to use new decorator.
TEST PLAN
Add one of these decorators to a test
Edit a test to pass on the first invocation, confirm test appears as pass
Edit a test to pass on the first invocation, pass on the second, confirm test appears as xfail
Edit a test to fail on two consecutive runs, confirm test appears in results as fail/error

Summary:
This removes a lot of boilerplate, which was needed to execute monitor operations. Previously one
needed do declare a separate class for each operation which would manually capture all needed
arguments, which was very verbose. In addition to less code, I believe this also makes the code
more readable, since now the implementation of the operation can be physically closer to the code
that invokes it.
Test Plan: Code compiles on x86, arm and mips, tests pass on x86 linux.

There are a couple of bugs in the XML register info handling which this patch fixes:
+ conflicting variable names in lambda, both capture list and parameters contains a variable called 'name'.
+ prev_reg_num, which sets the register number, should be incremented after each register is processed.
+ Windows errors regarding empty strings and the 'xi:' prefix disappearing from 'xi:include' node name.

- Don't have any header files claim to be part of the lldb-core target. If they are part of the lldb-core target then any file can just #include the header file name without the prefix (#include "Foo.h") when the cmake/make/other builds would require a full path (#include "lldb/Core/Foo.h"). This will help make sure the builds succeed on all platforms when changes are made on MacOSX.
- Add the Hexagon dynamic loader to the DynamicLoader plug-in folder so it gets compiled in MacOSX. There was a recent build bot failure that wasn't caught due to this code not being compile in the MacOSX build

A few extras were fixed
- Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected.
- Since some places want to access the address as a reference, I added a few new functions to symbol:
Address &Symbol::GetAddressRef();
const Address &Symbol::GetAddressRef() const;
Linux test suite passes just fine now.

The expression parser mode allows UnknownAnyTy to make it all the way through, but that is bad for ivars because it means type layout fails horribly (as in, clang crashes)
This patch fixes the issue by using the "variables view mode", which masks UnknownAnyTy as empty-type, and pointer-to UnknownAnyTy as void*
This, in turn, allows LLDB to properly reconstruct ivars of IMP type in ObjC type - as per accompanying test case
Fixes rdar://21471326

The language can not be definitively determined from the mangling, so
this new name helps clarify that fact. This addresses the concerns raised
in http://reviews.llvm.org/rL226962.

Summary:
the original bug was fixed (a rogue breakpoint messing up inferior data structures) and the tests
seems to pass now. Since android has a default SEGV handler, I have had to alter the test
expectation in this case.
Test Plan: Tests pass on android arm.

The tested functionality is implemented now. The test remains XTIMEOUTed, because it times out
occasionally, probably due to test suite deficiencies.

PT_GETREGS. Put all four on the same line for a more compact log. Also
use the proper 64-bit register names.

With the removal of ProcessLinux in r240543 this code is used only on
FreeBSD. FreeBSD isn't affected by whichever issue originally prompted
the addition of SetResumeState, so just remove it.
As discussed on the mailing list (and mentioned in a FIXME comment)
it shouldn't be called there.

Summary:
Currently, the local-only path fails about 50% of the tests, which means that: a) nobody is using
it; and b) the remote debugging path is much more stable. This commit removes the local-only
linux debugging code (ProcessLinux) and makes remote-loopback the only way to debug local
applications (the same architecture as OSX). The ProcessPOSIX code is moved to the FreeBSD
directory, which is now the only user of this class. Hopefully, FreeBSD will soon move to the new
architecture as well and then this code can be removed completely.
Test Plan: Test suite passes via remote stub.

* Add and fix the emulation of several instruction.
* Disable frame pointer usage on Android.
* Specify return address register for the unwind plan instead of explict
tracking the value of RA.
* Replace prologue detection heuristics (unreliable in several cases)
with a logic to follow the branch instructions and restore the CFI
value based on them. The target address for a branch should have the
same CFI as the source address (if they are in the same function).
* Handle symbols in ELF files where the symbol size is not specified
with calcualting their size based on the next symbol (already done
in MachO files).
* Fix architecture in FuncUnwinders with filling up the inforamtion
missing from the object file with the architecture of the target.
* Add code to read register wehn the value is set to "IsSame" as it
meanse the value of a register in the parent frame is the same as the
value in the current frame.

A "qSymbol::" is sent when shared libraries have been loaded by hooking into the Process::ModulesDidLoad() function from within ProcessGDBRemote. This function was made virtual so that the ProcessGDBRemote version is called, which then first calls the Process::ModulesDidLoad(), and then it queries for any symbol lookups that the remote GDB server might want to do.
This allows debugserver to request the "dispatch_queue_offsets" symbol so that it can read the queue name, queue kind and queue serial number and include this data as part of the stop reply packet. Previously each thread would have to do 3 memory reads in order to read the queue name.
This is part of reducing the number of packets that are sent between LLDB and the remote GDB server.

a hand-called function from the private state thread. The problem
was that on the way out of the private state thread, we try to drop
the run lock. That is appropriate for the main private state thread,
but not the secondary private state thread. Only the thread that
spawned them can know whether this is an appropriate thing to do or
not.

Enable ${language} to be specified in the frame-format string to see
the current frame's compile unit language in "frame info".
Test Plan:
debug a C++ program, run to main, and run the lldb commands:
settings set frame-format "frame lang=${language}\n"
frame info
you should see:
frame lang=c++
test case added in:
./dotest.py --executable lldb -f SettingsCommandTestCase.test_set_frame_format
