Add hardware division as a default feature on Cortex-A15. Also add test cases to check this, and change diagnostics for the hwdiv-arm feature to something useful.

This commit adds an example python file that can be used with 'target-definition-file' setting for Linux gdbserver.
This file has an extra key 'breakpoint-pc-offset' that LLDB uses to determine how much to change the PC
after hitting the breakpoint.

There are targets that support i128 sized scalars but cannot emit
instructions that modify them directly.  The proper thing to do is to
emit a libcall.

This fixes PR17481.

If we have multiple definitions of the same entity from different modules, we
nominate the first definition which we see as being the canonical definition.
If we load a declaration from a different definition and we can't find a
corresponding declaration in the canonical definition, issue a diagnostic.

This is insufficient to prevent things from going horribly wrong in all cases
-- we might be in the middle of emitting IR for a function when we trigger some
deserialization and discover that it refers to an incoherent piece of the AST,
by which point it's probably too late to bail out -- but we'll at least produce
a diagnostic.

queue name out of ProcessGDBRemote and in to the Platform
plugin, specifically PlatformDarwin.

Also add a Platform method to translate a dispatch_quaddr
to a QueueID, and a Thread::GetQueueID().

I'll add an SBThread::GetQueueID() next.

r177003 applied the late parsed template technique to friend functions
but omitted the corresponding check for redefinitions.

This patch adds the same check already in use for templates to the
new code path in order to diagnose and reject invalid redefinitions
that were being silently accepted.

Fixes PR17324.

Delayed exception specification checking for defaulted members and virtual
destructors are both susceptible to mutation during iteration so we need to
swap and process the worklists.

This resolves both accepts-invalid and rejects-valid issues and moreover fixes
potential invalid memory access as the contents of the vectors change during
iteration and recursive template instantiation.

Checking can be further delayed where parent classes aren't yet fully defined.
This patch adds two assertions at end of TU to ensure no specs are left
unchecked as was happenning before the fix, plus a test case from Marshall Clow
for the defaulted member crash extracted from the libcxx headers.

False. GCC does not accept [[gnu::warn_unused]], not to be confused with [[gnu::warn_unused_result]] which does exist.

INT 3 (machine code 0xCC) will raise an interrupt when executed. That is better
for filling the gap than NOP because we want to stop the execution immediately
when the control reached to non-code address.

There is no test as currently there is no call to the NativeWriter.

Future commits will add calls to the NativeWriter.

Instead of showing multiple lines of debug messages, show only one message
by CompareAtoms::operator(). Here is an example.

Before:
  Sorting _main .text
  Sorting by sectionPos(2,2)
  Sorting by override
  Sorting _main .text
  Sorting by sectionPos(2,2)
  Sorting by override

After:
  Layout: '_main' > '.text' (override (1, 0))
  Layout: '_main' > '.text' (override (1, 0))

This caused the clang-native-mingw32-win7 buildbot to break.

The assembler was complaining about the following lines that were showing up
in the asm for CrashRecoveryContext.cpp:

  movl  $"__ZL16ExceptionHandlerP19_EXCEPTION_POINTERS@4", 4(%eax)
  calll "_AddVectoredExceptionHandler@8"
  .def   "__ZL16ExceptionHandlerP19_EXCEPTION_POINTERS@4";
  "__ZL16ExceptionHandlerP19_EXCEPTION_POINTERS@4":
  calll "_RemoveVectoredExceptionHandler@4"

Reverting for now.

Also fix a bug where long-running processes could eventually trigger a crash in
the runtime by filling up the cache. I've not found a nice way to add a test for
this crasher; ideas welcome.

::Fork already does this internally, so this was simply leaking file handles.

This fixes the problem where the test suite would occasionally run out of file handles.
