[mips64] Emit correct addend for some PC-relative relocations

Browse Source 
So far, LLVM has not emitted correct addend for N64 and N32 ABI. This patch
fixes that. It also removes fixup from MCJIT for R_MIPS_PC16 relocation.

Patch by Vladimir Radosavljevic.

Differential Revision: http://reviews.llvm.org/D10565


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@240404 91177308-0d34-0410-b5e6-96231b3b80d8
