Improve TLS support on TILE-Gx/TILEPro:
- Add support for TLS LE references. - Support linker optimization of TLS references. - Delete relocations of GOT/tp relative offsets beyond 32-bits. This brings binutils in line with the support expected in gcc 4.7, for TILE-Gx/TILEPro. bfd/ * reloc.c: Add BFD_RELOC_TILEPRO_TLS_GD_CALL, BFD_RELOC_TILEPRO_IMM8_X0_TLS_GD_ADD, BFD_RELOC_TILEPRO_IMM8_X1_TLS_GD_ADD, BFD_RELOC_TILEPRO_IMM8_Y0_TLS_GD_ADD, BFD_RELOC_TILEPRO_IMM8_Y1_TLS_GD_ADD, BFD_RELOC_TILEPRO_TLS_IE_LOAD, BFD_RELOC_TILEPRO_IMM16_X0_TLS_LE, BFD_RELOC_TILEPRO_IMM16_X1_TLS_LE, BFD_RELOC_TILEPRO_IMM16_X0_TLS_LE_LO, BFD_RELOC_TILEPRO_IMM16_X1_TLS_LE_LO, BFD_RELOC_TILEPRO_IMM16_X0_TLS_LE_HI, BFD_RELOC_TILEPRO_IMM16_X1_TLS_LE_HI, BFD_RELOC_TILEPRO_IMM16_X0_TLS_LE_HA, BFD_RELOC_TILEPRO_IMM16_X1_TLS_LE_HA, BFD_RELOC_TILEGX_IMM16_X0_HW0_TLS_LE, BFD_RELOC_TILEGX_IMM16_X1_HW0_TLS_LE, BFD_RELOC_TILEGX_IMM16_X0_HW0_LAST_TLS_LE, BFD_RELOC_TILEGX_IMM16_X1_HW0_LAST_TLS_LE, BFD_RELOC_TILEGX_IMM16_X0_HW1_LAST_TLS_LE, BFD_RELOC_TILEGX_IMM16_X1_HW1_LAST_TLS_LE, BFD_RELOC_TILEGX_TLS_GD_CALL, BFD_RELOC_TILEGX_IMM8_X0_TLS_GD_ADD, BFD_RELOC_TILEGX_IMM8_X1_TLS_GD_ADD, BFD_RELOC_TILEGX_IMM8_Y0_TLS_GD_ADD, BFD_RELOC_TILEGX_IMM8_Y1_TLS_GD_ADD, BFD_RELOC_TILEGX_TLS_IE_LOAD, BFD_RELOC_TILEGX_IMM8_X0_TLS_ADD, BFD_RELOC_TILEGX_IMM8_X1_TLS_ADD, BFD_RELOC_TILEGX_IMM8_Y0_TLS_ADD, BFD_RELOC_TILEGX_IMM8_Y1_TLS_ADD.
