Bruno Cardoso Lopes d2d45a5575 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

Bruno Cardoso Lopes 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

Daniel Dunbar 0dd5e1ed39 More migration to raw_ostream, the water has dried up around the iostream hole.
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

Bruno Cardoso Lopes 40ca1f1c2e 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

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

Bruno Cardoso Lopes 50bf9a60e5 Use R_X86_64_32S to handle Jump Table Index relocation entries. Hide TAI usage inside getSection* functions

Bruno Cardoso Lopes e376b53c7b Use a better name for the label relocations while emitting them for Jump Tables

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

Bruno Cardoso Lopes 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.

Torok Edwin fbcc663cbf 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").

Torok Edwin 56d0659726 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.
