add support for PtrToInt, Add, Mul.

Handle large integers, x86_fp80, ConstantAggregateZero, and two more ConstantExpr:
GetElementPtr and IntToPtr
Set SHF_MERGE bit for mergeable strings
Avoid zero initialized strings to be classified as a bss symbol
Don't allow common symbols to be classified as STB_WEAK
Add a constant to be used as a global value offset in data relocations

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

the computed symbol offset directly

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

llvm-svn: 76347

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

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

Add section symbols to the symbol table

llvm-svn: 74170

Only pad when the section size > 0 and move the code that deals
with globals initializers to a place we know for sure the global
is initialized.

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

Introduce new BinaryObject (blob) class, ELF Writer modified to use it. BinaryObject.h by Aaron Gray

llvm-svn: 73333

Function alignment can be computed for each target using TargetELFWriterInfo
