This patch fixes the MC object emission of 'nop' for external function calls

and also fixes the R_PPC64_TOC16 and R_PPC64_TOC16_DS relocation offset.
The 'nop' is needed so a restore TOC instruction (ld r2,40(r1)) can be placed
by the linker to correct restore the TOC of previous function.

Current code has two issues: it defines in PPCInstr64Bit.td file a LDinto_toc
and LDtoc_restore as a DSForm_1 with DS_RA=0 where it should be
DS=2 (the 8 bytes displacement of the TOC saving). It also wrongly emits a
MC intruction using an uint32_t value while the PPC::BL8_NOP_ELF
and PPC::BLA8_NOP_ELF are both uint64_t (because of the following 'nop').

This patch corrects the remaining ExecutionEngine using MCJIT:
