72dd2eef36 ELF improvements: 
Handle large integers, x86_fp80, ConstantAggregateZero, and two more ConstantExpr:
GetElementPtr and IntToPtr
Set SHF_MERGE bit for mergeable strings
Avoid zero initialized strings to be classified as a bss symbol
Don't allow common symbols to be classified as STB_WEAK
Add a constant to be used as a global value offset in data relocations

2b1dc9a783 - Remove custom handling of jumptables by the elf writter (this was 
a dirty hack and isn't need anymore since the last x86 code emitter patch)
- Add a target-dependent modifier to addend calculation
- Use R_X86_64_32S relocation for X86::reloc_absolute_word_sext
- Use getELFSectionFlags whenever possible
- fix getTextSection to use TLOF and emit the right text section 
- Handle global emission for static ctors, dtors and Type::PointerTyID
- Some minor fixes

51d5b43cda refactor section construction in TLOF to be through an explicit 
initialize method, which can be called when an MCContext is available.

149465ea06 Eliminate SectionFlags, just embed a SectionKind into Section 
instead and drive things based off of that.

12e543228d Support adding relocations for data sections, handling the cases where 
global declared symbols are initialized with references from other global
symbols.

447b7fd4bb For PC relative relocations where symbols are defined in the same section they 
are referenced, ignore the relocation entry and patch the relocatable field with
the computed symbol offset directly

484e90b45e Add support to properly reference private symbols on relocation entries. 
Use proper relocation type to build relocations for JumpTables (rodata
sections).

2717863900 use std::vector instead of std::list for both Section and Symbol lists because 
we care more about random access than insertion/deletion of elements.

02a9191b71 Use a default alignment for data and bss sections. 
Only pad when the section size > 0 and move the code that deals
with globals initializers to a place we know for sure the global
is initialized.

12ad90a7a6 ELF Code Emitter now uses CurBufferPtr, BufferBegin and BufferEnd, as do JIT and 
MachO Writer. This will change with the arrival of ObjectCodeEmitter and
BinaryObject

adding <map> to many files that actually do need it.

e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.
