This doesn't use formated_raw_ostream because it doesn't support the

3605f8423f Introduce llvm-cov. 
Add llvm-cov skeleton. It has initial support to read coverage info generated by GCOVProfiling.cpp. 
Today, you can do
prompt> clang a.c -ftest-coverage -fprofile-arcs -o a
prompt> ./a
prompt> llvm-cov -gcno a.gcno -gcda a.gcda

92ffa08e9a Remove llvmc and assorted build machinery for it. 
The problems that llvmc solved have largely been subsumed with the
tasks that the clang driver can accomplish, but llvmc lacks flexibility
and depends too heavily on the EOL'd llvm-gcc.

82df2a3e37 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.

de2d3cf093 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.

b08f6dc724 llvm-dwarfdump: Make the "is debug info section" heuristic stricter so it doesn't accidentaly picks up the wrong section.

52607b3842 Object: make the following changes into SymbolRef 
- Add enum SymbolType and function getSymbolType()
- Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions.
- Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address.
- Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.

6b456ffb42 DWARF: Port support for parsing .debug_aranges section from LLDB and wire it up to llvm-dwarfdump. 
This is only one half of it, the part that caches address ranges from the DIEs when .debug_aranges is
not available will be ported soon.

c4e7a56915 Sketch out a DWARF parser. 
This introduces a new library to LLVM: libDebugInfo. It will provide debug information
parsing to LLVM. Much of the design and some of the code is taken from the LLDB project.

It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an
object file. It can be used to write tests for DWARF input and output easily.

bd939ad83e Don't drop alignment info on local common symbols. 
- On COFF the .lcomm directive has an alignment argument.
- On ELF we fall back to .local + .comm
