Thumb32 assembler (64/69)

[Zack Weinberg <zack at codesourcery dot com>]

Add BFD_RELOC_ constants for the new relocations, and prune a couple
that are never used.

bfd:
	* reloc.c: Reorganize ARM relocations.  Remove from the
	assembler-only section all relocations that do in fact appear in
	object files.  Document more relocations.
	(BFD_RELOC_ARM_GOT12, BFD_RELOC_ARM_COPY): Delete - never generated.
	* bfd-in2.h, libbfd.h: Regenerate.
	* elf32-arm.c: Remove reference to BFD_RELOC_ARM_COPY.
gas:
	* config/tc-arm.h: Remove reference to BFD_RELOC_ARM_GOT12.
