d163e8b14c Remove hack used to strip unwanted chars from section name 
Use MCSectionELF methods as much as possible, removing some
ELFWriter methods which are now unused

3e0094d969 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

52d0851446 - 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

5fe575ff4f Eliminate SectionFlags, just embed a SectionKind into Section 
instead and drive things based off of that.

0a38dc5fda 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

4b70fab658 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.

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.

3e15bf33e0 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.
