Peter Collingbourne 62e4fc48a5 llvm-readobj: Fix addend in relocations for android packed format 
If a relocation group doesn't have the RELOCATION_GROUP_HAS_ADDEND_FLAG set, then this implies the group's addend equals zero.
In this case android packed format won't encode an explicit addend delta, instead we need to set Addend, the "previous addend" variable, to zero by ourself.

Peter Collingbourne cf017ada68 llvm-readobj: fix printing number of relocations in Android packed format. 
With '-elf-output-style=GNU -relocations', a header containing the number
of entries is printed before all the relocation entries in the section.
For Android packed format, we need to perform the unpacking first before
we can get the actual number of relocations in the section.

Peter Collingbourne 689e6c052e llvm-readobj: Add support for reading relocations in the Android packed format. 
This is in preparation for testing lld's upcoming relocation packing
feature (D39152). I have verified that this implementation correctly
unpacks the relocations from a Chromium DSO built with gold and the
Android relocation packer for ARM32 and ARM64.
