b089483993 Use getNumOperands() instead of Operands.size(). 
The representation of the Operands array is going to change soon so it
can be allocated from a BumpPtrAllocator.

76268ac682 X86: Turn mul of <4 x i32> into pmuludq when no SSE4.1 is available. 
pmuludq is slow, but it turns out that all the unpacking and packing of the
scalarized mul is even slower. 10% speedup on loop-vectorized paq8p.

b2f0a2bd4b X86: Emit vector sext as shuffle + sra if vpmovsx is not available. 
Also loosen the SSSE3 dependency a bit, expanded pshufb + psra is still better
than scalarized loads. Fixes PR14590.

c9dcbe6987 Use a negative value to represent INVALID_SIMPLE_VALUE_TYPE instead of 256. Its much cheaper for the isSimple() checks to look for values less than 0 rather than a value greater than 255. This shaves ~8k off the size of the llc binary on x86-64.

d5aae980cb In some cases, due to scheduling constraints we copy the EFLAGS. 
The only way to read the eflags is using push and pop. If we don't
adjust the stack then we run over the first frame index. This is
not something that we want to do, so we have to make sure that
our machine function does not copy the flags. If it does then
we have to emit the prolog that adjusts the stack.

segment name to get to the section name.

a9f810b6b5 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 :-)
