[PATCH] D18624: [PGO] PGOFuncName meta data if PGOFuncName is different from function's raw name.

Write out the PGOFuncName meta data if PGOFuncName is different from function's raw name. This should only apply to internal linkage functions. This is to be consumed by indirect-call promotion when called in LTO optimization passes (D17864 under review).

This patch depends on http://reviews.llvm.org/D18623.
