Adhemerval Zanella 1ae2248e14 PowerPC: EH adjustments 
This patch adjust the r171506 to make all DWARF enconding pc-relative
for PPC64. It also adds the R_PPC64_REL32 relocation handling in MCJIT
(since the eh_frame will not generate PIC-relative relocation) and also
adds the emission of stubs created by the TTypeEncoding.

Adhemerval Zanella 9b0b781395 PowerPC: Fix eh_frame relocation for PIC 
This patch fixes the PPC eh_frame definitions for the personality and 
frame unwinding for PIC objects. It makes PIC build correctly creates
relative relocations in the '.rela.eh_frame' segments and thus avoiding
a text relocation that generates a DT_TEXTREL segments in link phase.

Ulrich Weigand 9e159fd7a0 Fix initial frame state on powerpc64. 
The createPPCMCAsmInfo routine used PPC::R1 as the initial frame
pointer register, but on PPC64 the 32-bit R1 register does not
have a corresponding DWARF number, causing invalid CIE initial
frame state to be emitted.  Fix by using PPC::X1 instead.
