sends the chars in hex format if needed.

frames, UnwindLLDB could create the incorrect RegisterContext for a given
stack frame because it was using the frame index (not the concrete frame
index). This was causing crashes when doing backtraces through the 
SBFrame::GetFP() because a NULL register context was being returned for the
deepest stack frame.

was being searched and sorted using a shared pointer as the value which means
the pointer value was what was being searched for. This means that anytime
you did a stack backtrace, the collection of FuncUnwinders doubled and then
the array or shared pointer got sorted (by pointer value), so you had an ever
increasing collection of shared pointer where a match was never found. This
means we had a ton of duplicates in this table and would cause issues after
one had been debugging for a long time.

Instead encode llvm IR level property "HasSideEffects" in an operand (shared
with IsAlignStack). Added MachineInstrs::hasUnmodeledSideEffects() to check
the operand when the instruction is an INLINEASM.

This allows memory instructions to be moved around INLINEASM instructions.

Revert r122955. It seems using movups to lower memcpy can cause massive regression (even on Nehalem) in edge cases. I also didn't see any real performance benefit.
