49d508fd19 Jim Asked us to move DataLayout on ARM back to the most specialized classes. Do
so and also change X86 for consistency.

Investigating if this can be improved a bit.

2ae97a2777 - 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

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

b47b093de2 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

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

e0b1ee937a Don't attribute in file headers anymore. See llvmdev for the
discussion of this change.  Boy are my fingers tired. ;-)
