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

global declared symbols are initialized with references from other global
symbols.

are referenced, ignore the relocation entry and patch the relocatable field with
the computed symbol offset directly

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

Use proper relocation type to build relocations for JumpTables (rodata
sections).

we care more about random access than insertion/deletion of elements.

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").

llvm-svn: 75640

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.

Support for .text relocations, implementing TargetELFWriter overloaded methods for x86/x86_64.
Use a map to track global values to their symbol table indexes

Emission for globals, using the correct data sections

rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

now cerr, cout, and NullStream resp.
