  37 Routine Description:
  38   Performs an x64 specific relocation fixup
  39
  40 Arguments:
  41   Reloc      - Pointer to the relocation record
  42   Fixup      - Pointer to the address to fix up
  43   FixupData  - Pointer to a buffer to log the fixups
  44   Adjust     - The offset to adjust the fixup

  46 Returns:
  47   EFI_UNSUPPORTED - relocate unsupported

  59 Routine Description:
  60
  61   Returns TRUE if the machine type of PE/COFF image is supported. Supported
  62   does not mean the image can be executed it means the PE/COFF loader supports
  63   loading and relocating of the image type. It's up to the caller to support
  64   the entry point.
  65
  66   This function implies the basic PE/COFF loader/relocator supports IA32, EBC,
  67   & X64 images. Calling the entry point in a correct mannor is up to the
  68   consumer of this library.
  69
  70 Arguments:
  71
  72   Machine   - Machine type from the PE Header.
  73
  74 Returns:
  75
  76   TRUE      - if this PE/COFF loader can load the image
  77   FALSE     - if this PE/COFF loader cannot load the image
