George Rimar 9413fa26af Revert r251536 as it broke buildbot: http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-ubuntu-fast/builds/2104

George Rimar 06f4e43d29 [ELF2] R_X86_64_64 plt relocation implemented. 
This little patch is a final point in fix for https://llvm.org/bugs/show_bug.cgi?id=25175.

It`s make sample from issue description to work with -O0 optimization flag (with -O0 it generates R_X86_64_64 plt relocation).

Michael J. Spencer 52bf0ebfdf [lld][elf2] Sort output sections. 
Sort by:
ALLOC
ALLOC && NOBITS
ALLOC & EXEC
ALLOC & EXEC && NOBITS
ALLOC & WRITE
ALLOC & WRITE && NOBITS
<nothing> (ignoring NOBITS)

The dynamic section is finalized early because it adds strings to the dynamic string table, which comes before the dynamic table.

Rui Ueyama 2dfd74f758 ELF2: Add DT_REL{,A}ENT and DT_SYMENT. 
According to the ELF specification, these dynamic array entries are mandatory.

Michael J. Spencer 55f56320c7 [elf2] Fix dynamic-reloc.s test. 
The offset of the .rela.dyn section isn't the same between hosts because a path comes before it. This test doesn't care what the offset is.

Rafael Espindola 6569522f4b Relax the test to fix some bots. 
The string table contains a file path, so addresses and offsets can be
different on some setups.

Rafael Espindola 2b92d8f184 Move code computing NumEntries to finalize. 
When DynamicSection is constructed we still don't know if there will be
any dynamic relocations or not.

Rafael Espindola 19e3889dba Start creating dynamic relocations. 
For now we don't create got/plt and only Elf_Rela is supported.
