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 pass.
