cl is not attempting to complete a templated class when used in this
context. The conversion forces this to happen.

Thanks to Richard Smith for figuring this out.

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.

llvm-svn: 166700

  * 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.

  * 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.

of this is derived from the Mach-O writer.  Reviewed by: Nick Kledzik.
 * Adds loop to SectionChunk::write traverse references calling the
   writer's fixup handler, applyFixup.
 * Adds method, ELFWriter::buildAtomToAddressMap to that creates a
   mapping from an atom to its runtime address.
 * Adds method, ELFWriter::addressOfAtom to return the runtime address
   of the atom.

Although the code is not valid to begin with. It is trying to do a raw memory
copy of a non standard-layout type. nameoffset is not guaranteed to directly
follow cmdsize.

This should be properly fixed.

Add 'invalid' as a Reference Kind so that unknown/invalid kind strings can return that fact to the caller for use in constructing an error message, rather that triggering an assertion.
