	* Migrate on LLVM@r152063
	* Migrate on clang@r152062

	* LD/LDSection, LD/ELFFileFormat, LD/ELFDynObjFileFormat,
	  LD/ELFExecFileFormat:
	Support setting alignment constraint in section header.
	* LD/Layout:
	Update sections' alignment constraints during section merging. 

	* Support/MemoryArea, Support/MemoryRegion:
	Enhance memory utilities. 

	* Target/ARMLDBackend:
	1. work around ARM.exidx and ARM.extab.
	2. add relocation supports - R_ARM_TARGET1, R_ARM_TARGET2, R_ARM_ABS32, 
	R_ARM_BASE_PREL, and R_ARM_GOT_PREL

	* Target/MipsLDBackend:
	1. Android bitmap, native Plasma and Quake1 is examined successfully.

	* Target/GNULDBackend, LD/ELFSegmentFactory:
	Move segment-related implemenation out of GNULDBackend.

	* Support/ScopedWriter:
	Obsolete, removed.

	* MC/SymbolCategory:
	add random accessing functions

	* add test/ARM/Relocation:
	* add test/ARM/GOTPLT:
	Simple regression testcases. Each case is used for testing a single
	relocation or GOTPLT entry.

	* add test/Android/Plasma/ARM, X86, MIPS:
	* add test/Android/Quake/ARM, X86:
	* add test/Android/Quake2/ARM, X86:
	Basic regression testcases for Android platform. The system libraries
	for each platform are under test/libs/ARM, X86, MIPS.

	* Target/TargetLDBackend:
	separate readSections() into readRegularSection() and
	readTargetSection().

	* Target/GNULDBackend:
	Move hash_bucket_count() and isDynamicSymbol() on successors.

	* Target/MipsLDBackend: Eable to link trivial cases and Android Plasma.
	* Target/X86LDBackend: Eable to link all Android JNI cases with CRT.

	* CodeGen/SectLinkerOption, llvm-mcld.cpp:
	get rid of -dB option. MCLinker does not need to ask users for -dB
	option.

	* MC/MCLinker, LD/ELFObjectReader, LD/ELFObjectWriter:
	Support symbol visibility.

	* LD/LDSection: Separate LinkInfo into Link and Info. 

	* LD/Relocation:
	In order to enhance memory footprints:
	1. Remove Relocation::m_Parent.
	2. Let target data be a copy, not a pointer.

	* LD/ELFReader, LD/ObjectReader, LD/ELFObjectReader, LD/Layout:
	Support GROUPT section.

	* LD/LDFileFormat:
	Support all special sections listed in Linux Standard Base
	(ISO/IEC 23360).

	* Support/GCFactoryListTraits:
	Provides GCFactory's trait for llvm::iplist.

	* Support/LEB128: Add LEB128 utilities.

	* Support/HashTable:
	Identify ambiguous constructors by adding an anonyous parameter.

	* Suppot/MemoryRegion, Support/MemoryArea:
	1. remove pIsWrite parameter in MemoryArea::request(). MemoryArea knows
	the file is readable or writable when map() the file.
	2. MemoryArea allows to request a zero size MemoryRegion.

	* patch/LLVM.patch: complement llvm/Support/ELF.h.
	Add SHT_GNU_ATTRIBUTES, SHT_GNU_HASH, SHT_GNU_verdef, SHT_GNU_verneed,
	and SHT_GNU_versym.

	* LD/Layout:
	1. Work around LDFileFormat::Exception and LDFileFormat::Version.
	2. appendFragment(): Support merging sections with different alignment
	constraints.
