Fix style while I'm here.

Rui Ueyama e3fbc89c44 ELF2: Do not use host pointer size to calculate x86_64 relocation addresses. 
Previous code had a potential portability issue because intptr_t is
not guaranteed to be 64 bit.

Rafael Espindola 3ef3a4c9ff Start adding support for static programs using dynamic libraries. 
This is just enough for a hello world using a dynamic glibc.

Simon Atanasyan 49829a1bfe [ELF2] Add initial MIPS support 
Besides a trivial MIPS support the patch introduces new TargetInfo class
member getDefaultEntry() to override default name of the entry symbol.
MIPS uses __start for that.

Rafael Espindola 0872ea3954 Simplify with some ideas from COFF: 
* add using namespace llvm::support::endian.
* create a add32le static helper.

Thanks to Rui for the suggestion.

Rafael Espindola cdfecffd80 Add support for relocating R_X86_64_GOTPCREL.

Rafael Espindola 7f07442bb6 Move the last remaining hard coded relocations to Target. 
Unfortunately the i386 and x86_64 relocation have the same numerical value
and it is a probably a bit much to add got support for another architecture
just to test this.

Rafael Espindola 1d6063e804 Stub out ARM and PPC targets so that we can use a switch to create them.

Rafael Espindola 3efa4e982e Add a token ppc64 reloc just to have a test showing that we handle BE.

Rafael Espindola c40108858d Move relocation processing to Target. 
I will add a couple of ppc64 relocs in the next patches.

Rafael Espindola 8c21fad1e8 Fix a merge problem. 
r248289 got lots when I moved code to Target.cpp. Sorry about that.

Rafael Espindola 01205f79a4 Start adding target abstractions. 
This is just enough to get PLT working on 32 bit x86.

The idea behind using a virtual interface is that it should be easy to
convert any of the functions to template parameters if any turns out to be
performance critical.
