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

68491c1217 Support adding relocations for data sections, handling the cases where
global declared symbols are initialized with references from other global
symbols.

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

e2b0ecd8be Use R_X86_64_32S to handle Jump Table Index relocation entries. Hide TAI usage inside getSection* functions

171375f73a Add support to properly reference private symbols on relocation entries.
Use proper relocation type to build relocations for JumpTables (rodata
sections).

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.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

c25e7581b9 assert(0) -> LLVM_UNREACHABLE.
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.
