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.
