This patch adds the following target relocations:

 - BFD_RELOC_HI16_S		High 16-bit relocation, for used with signed
   asm: ha()			lower.
 - BFD_RELOC_HI16_S_GOTOFF	High 16-bit GOT offset relocation for local
   asm: gotoffha()		symbols, for use with signed lower.
 - BFD_RELOC_OR1K_TLS_IE_AHI16	High 16-bit TLS relocation with initial
   asm: gottpoffha()		executable calculation, for use with signed
				lower.
 - BFD_RELOC_OR1K_TLS_LE_AHI16	High 16-bit TLS relocation for local executable
   asm: tpoffha()		variables, for use with signed lower.

 - BFD_RELOC_OR1K_SLO16		Split lower 16-bit relocation, used with
   asm: lo()			OpenRISC store instructions.
 - BFD_RELOC_OR1K_GOTOFF_SLO16	Split lower 16-bit GOT offset relocation for
   asm: gotofflo()		local symbols, used with OpenRISC store
				instructions.
 - BFD_RELOC_OR1K_TLS_LE_SLO16	Split lower 16-bit relocation for TLS local
   asm: tpofflo()		executable variables, used with OpenRISC store
				instructions.
