Jason Molenda 113f2d5289 Tighten up the 'log enable lldb unwind' printing for 
the arm emulate instruction unwinder so you can leave it
on by default and not be overwhelmed.  Set verbose mode to
get the full story on how the unwindplans were created.

Jakob Stoklund Olesen e2c92a3112 Spill mode: Hoist back-copies locally. 
The leaveIntvAfter() function normally inserts a back-copy after the
requested instruction, making the back-copy kill the live range.

In spill mode, try to insert the back-copy before the last use instead.
That means the last use becomes the kill instead of the back-copy.  This
lowers the register pressure because the last use can now redefine the
same register it was reading.

This will also improve compile time: The back-copy isn't a kill, so
hoisting it in hoistCopiesForSize() won't force a recomputation of the
source live range.  Similarly, if the back-copy isn't hoisted by the
splitter, the spiller will not attempt hoisting it locally.

Jakob Stoklund Olesen e8339b2e63 Disable local spill hoisting for non-killing copies. 
If the source register is live after the copy being spilled, there is no
point to hoisting it.  Hoisting inside a basic block only serves to
resolve interferences by shortening the live range of the source.

Eli Friedman 9bb51adcce Tweak *mmintrin.h so that they don't make any bad assumptions about alignment (which probably has little effect in practice, but better to get it right). Make the load in _mm_loadh_pi and _mm_loadl_pi a single LLVM IR instruction to make optimizing easier for CodeGen.

Ivan Krasin 639222d090 use 64-bit types instead of off_t/size_t to avoid the issue when 
gold plugin is built with Large File Support (sizeof(off_t) == 64 on i686)
and the rest of LLVM is built w/o Large File Support
(sizeof(off_t) == 32 on i686) which corrupts the stack.

Jim Ingham 8314c5259d Track whether a process was Launched or Attached to. If Attached, the detach when the debugger is destroyed, rather than killing the process. Also added a Debugger::Clear, which gets called in Debugger::Destroy to deal with all the targets in the Debugger. Also made the Driver's main loop call Destroy on the debugger, rather than just Destroying the currently selected Target's process.

SplitKit instead of by InlineSpiller.  This hidden command line option
