3483574772 Change ELFCodeEmitter logic to emit the constant pool and jump tables to 
their appropriate sections before the code itself. They need to be emitted
before the function because on some targets (x86 but not x86_64) the later
may reference a JT or CP entry address

2015382398 Support adding relocations for data sections, handling the cases where 
global declared symbols are initialized with references from other global
symbols.

84568ea6f1 Use R_X86_64_32S to handle Jump Table Index relocation entries. Hide TAI usage inside getSection* functions

d5eafae1fd Add support to properly reference private symbols on relocation entries. 
Use proper relocation type to build relocations for JumpTables (rodata
sections).

7bdb20f6a2 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.

f955a6ef49 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").

ae8a3ff177 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.

MachO Writer. This will change with the arrival of ObjectCodeEmitter and
BinaryObject
