c6615227ee Thumb32 assembler. 
* include/elf/arm.h: Import full set of relocation names from
	latest AAELF.  Make the primary name of all relocations be the one
	AAELF specifies.  Provide aliases under the traditional names.
	Kill FIRST_INVALID_RELOC_* and LAST_INVALID_RELOC_*.
	* bfd/reloc.c: Reorganize ARM relocations.  Remove ARM relocations
	that are never generated.  Document more of the relocations.  Add
	relocations for Thumb32.
	* bfd/libbfd.h, bfd/bfd-in2.h: Regenerate.
	* bfd/elf32-arm.c: Reorganize howto tables.  Implement Thumb32
	relocations.
	* ld/testsuite/ld-arm/mixed-app.d: Adjust expectations for
	renamed relocations.

	* gas/hash.c (hash_find_n): New interface.
	* gas/hash.h: Prototype it.

	* gas/config/tc-arm.c: Rewrite and reorganize.  Implement 32-bit
	Thumb instructions.
	* gas/testsuite/gas/arm: Convert all "gas_test" style tests to
	"run_dump_test" style tests, for more thorough testing.  Make
	adjustments to expectations where necessary.
	* gas/testsuite/gas/arm/t16-bad.s, gas/testsuite/gas/arm/tcompat.s
	* gas/testsuite/gas/arm/tcompat2.s, gas/testsuite/gas/arm/thumb32.s:
	New test cases.

	* opcodes/arm-dis.c: Add support for Thumb32 instructions and
	16-bit V6T2 instructions.
