Rafael Espindola bc8016d062 Add a funciton 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 informing
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.

Chandler Carruth 4d88a1c233 Sort the #include lines for tools/... 
Again, tools are trickier to pick the main module header for than
library source files. I've started to follow the pattern of using
LLVMContext.h when it is included as a stub for program source files.

Kevin Enderby badd100c26 Fixed a bug in llvm-objdump when disassembling using -macho option for a binary 
containing no symbols.  Fixed the crash and fixed it not disassembling anything.

Kevin Enderby edd5872f33 Fixed a bug in llvm-objdump when disassembling using -macho option for a binary 
that has more than one symbol.  The last symbol was not being disassembled to
the end of the section.

Craig Topper 54bfde79db Make MCInstrInfo available to the MCInstPrinter. This will be used to remove getInstructionName and the static data it contains since the same tables are already in MCInstrInfo.

Danil Malyshev cbe72fc959 Fixed ObjectFile functions: 
- getSymbolOffset() renamed as getSymbolFileOffset()
- getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile.
- added getRelocationOffset()
- fixed MachOObjectFile::getSymbolSize()
- fixed MachOObjectFile::getSymbolSection()
- fixed MachOObjectFile::getSymbolOffset() for symbols without section data.

Benjamin Kramer 43a772eda1 Add a MachO-specific "mode" to llvm-objdump, that, if enabled, gathers additional information that are only available on MachO. 
- It can take FunctionStarts from a binary to find entry points more accurately.
- Symbol offsets in executables are correct now.
