Before revision 171146, function 'PerformTruncateCombine' used to perform
a premature lowering of TRUNCATE dag nodes.
Revision 171146 then moved all the logic implemented by PerformTruncateCombine
to a custom lowering hook. However, that revision forgot to delete
function PerformTruncateCombine from the code.

This patch removes function 'PerformTruncateCombine' since it has no effect
on the SelectionDAG. No functional change intended.

Summary: Allow calls with non legal integer types based on i8 and i16 to be processed by mips fast-isel.

Based on a patch by Reed Kotler.

Test Plan:
"Make check" test forthcoming.
Test-suite passes at O0/O2 and with mips32 r1/r2

This solves some false negatives at a cost of adding some false positives that
can be fixed easily and (almost) automatically.

This patch adds new default flag -fno-builtin which forces gcc to not optimize builtin functions.
For example, without this flag GCC replaces printf("hello\n") -> puts("hello") even if -O0 was specified

Also this patch fixes the MiDataTestCase.test_lldbmi_data_disassemble test on Linux/gcc.

sys/time.h on Solaris (and possibly other systems) defines "SEC" as "1"
using a cpp macro.  The result is that this fails to compile.

Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
   of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
   LineJoiner iterate over the lines so we never operate on a line that might
   be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.

Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
   only the outer expression was affected:
   int x = s({ // clang-format only this line
     class X {
       public:
    // ^ this starts at the non-modified indnent level; previously we would
    //   not fix this, now we correctly outdent it.
       void f();
     };
   });
2. We would incorrectly align comments across lines that do not have comments
   for lines with nested blocks:
   int expression; // with comment
   int x = s({
     int y; // comment
     int z; // we would incorrectly align this comment with the comment on
            // 'expression'
   });

Summary:
NPL::Resume attempted to handle eStateStopped as a resume action. However:
- GDBRemoteCommunicationServerLLGS (the only user of NPL) never sets this action
- it could set this action in response to a vCont:t packet, but LLDB never produces this packet
- gdb-remote protocol documentation says vCont:t packet is used only in non-stop mode, but LLDB
  does not support non-stop mode
- even if LLDB supported non-stop mode, this implementation of eStateStopped does something
  different from what the spec says it should (according to spec, it should stop the specified
  thread, but this seems to want to stop all threads).

Given the facts above, I believe we should remove this unused and untested code, as it probably
doesn't even work and removing it makes the rest of the code noticably simpler.

Summary:
Since the former-TSC events are now processed synchronously, there is no need for to protect them
with a separate mutex - all the actions are now guarded by the big m_threads_mutex.

With the mutex gone, the following functions, no longer have any purpose and were removed:
NotifyThreadCreate: replaced by direct calls to ThreadWasCreated
NotifyThreadStop: replaced by direct calls to ThreadDidStop
NotifyThreadDeath: folded into StopTrackingThread
ResetForExec: inlined as it consisted of a single line of code
RequestThreadResume(AsNeeded): replaced by direct calls to ResumeThread
StopThreads: removed, as it was never called

Test Plan: tests continue to pass

'schedule' clause for combined directives requires additional processing. Special helper variable is generated, that is captured in the outlined parallel region for 'parallel for' region. This captured variable is used to store chunk expression from the 'schedule' clause in this 'parallel for' region.

Besides class, function and file names, we also change the command line option
from -polly-codegen-isl to just -polly-codegen. The isl postfix is a leftover
from the times when we still had the CLooG based -polly-codegen. Today it is
just redundant and we drop it.

The MachO toolchain has an isTargetIOSBased method, but it isn't
virtual so it isn't very meaningful to call it. After thinking about
this, I guess that putting this logic in the MachO class is a bit of a
layering violation anyway. Do this more like how we handle
AddLinkRuntimeLibArgs instead.
