Since most content types (e.g. typeCode) have a 
preferred Permission, add a function to do that mapping.
Then hook up to YAML Reader and Writer such that
the 'permissions:' key does not need to be specified unless
overriding what the content type prefers.

With this hello world works with dietlibc on x86-64 Linux.

This is required for the loader to correctly set AT_PHDR.

With this lld can correctly link against dietlibc and get to main.

and adds a new file ReaderWriterYAML.cpp that uses YAML I/O.

Lots of tweaks to test suite for slightly different YAML encoding.

This patch changes the following:
  * Use conventional naming for KindHandlers.
  * Add X86 relocation routines.
  * Use std::function instead of function pointers in _fixupHandler map.
  * Change _fixupHandler map from std::map to llvm::DenseMap.
  * Add simple testcase for x86 relocations.

  * Moves enum Scope from DefinedAtom.h to Atom.h
  * Adds scope method to AbsoluteAtom class
  * Updates YAML to print scope of AbsoluteAtoms
  * Update Native Reader/Writer to handle this new, "attribute"
  * Adds testcase

  * Add relocation reference support for Hexagon and PowerPC.
    - Hexagon has many relocation types, this patch covers just
      a subset, more will be added.
    - PowerPC support was added so that we can verify mixed endian
      environments.
  * Add some basic test cases
  * Update ldd-core to accept -endian flag

Removed architecture dependent .sbss section creation.

Updated test case to show the change in section types and removal of a sbss section.

  * Return correct size and alignment for common symbols.

Reorganize to derive all sections from SectionChunk.
Construct section table header from SectionChunk.

llvm-svn: 164981

  * Updates ReaderELF.cpp contentType method to match ELF.h's logic and now handle
    typeData
  * Add -arch to ldd-core testdriver
  * Add testcase to check typeData
  * Update others to stay in sync with this change.
