cb6155ac8d Don't skip __DWARF, 
Now that we don't merge section and segment names, we don't need to skip the
segment name to get to the section name.

cca2985848 Add a function to get the segment name of a section. 
On MachO, sections also have segment names. When a tool looking at a .o file
prints a segment name, this is what they mean. In reality, a .o has only one
anonymous, segment.

This patch adds a MachO only function to fetch that segment name. I named it
getSectionFinalSegmentName since the main use for the name seems to be inform
the linker with segment this section should go to.

The patch also changes MachOObjectFile::getSectionName to return just the
section name instead of computing SegmentName,SectionName.

The main difference from the previous patch is that it doesn't use
InMemoryStruct. It is extremely dangerous: if the endians match it returns
a pointer to the file buffer, if not, it returns a pointer to an internal buffer
that is overwritten in the next API call.

We should change all of this code to use
support::detail::packed_endian_specific_integral like ELF, but since these
functions only handle strings, they work with big and little endian machines
as is.

I have tested this by installing ubuntu 12.10 ppc on qemu, that is why it took
so long :-)

80fefbe978 Fix a bug in the code that checks if we can vectorize loops while using dynamic 
memory bound checks.  Before the fix we were able to vectorize this loop from
the Livermore Loops benchmark:

for ( k=1 ; k<n ; k++ )
  x[k] = x[k-1] + y[k];

c000c3d36d Require the two-argument MI::addOperand(MF, MO) for dangling instructions. 
Instructions that are inserted in a basic block can still be decorated
with addOperand(MO).

Make the two-argument addOperand() function contain the actual
implementation. This function will now always have a valid MF reference
that it can use for memory allocation.

c81d04b28d Add an MF argument to MI::copyImplicitOps(). 
This function is often used to decorate dangling instructions, so a
context reference is required to allocate memory for the operands.
