or1k: Add relocations for high-signed and low-stores
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.
