Stefan Pintilie beb52b12cb [PowerPC] Support PCRelative Callees for R_PPC64_REL24 Relocation 
The R_PPC64_REL24 is used in function calls when the caller requires a
valid TOC pointer. If the callee shares the same TOC or does not clobber
the TOC pointer then a direct call can be made. If the callee does not
share the TOC a thunk must be added to save the TOC pointer for the caller.

Up until PC Relative was introduced all local calls on medium and large code
models were assumed to share a TOC. This is no longer the case because
if the caller requires a TOC and the callee is PC Relative then the callee
can clobber the TOC even if it is in the same DSO.

This patch is to add support for a TOC caller calling a PC Relative callee that
clobbers the TOC.
