[MC] Pass MCSymbolData to needsRelocateWithSymbol

As discussed in a previous checking to support the .localentry
directive on PowerPC, we need to inspect the actual target symbol
in needsRelocateWithSymbol to make the appropriate decision based
on that symbol's st_other bits.

Currently, needsRelocateWithSymbol does not get the target symbol.
However, it is directly available to its sole caller.  This patch
therefore simply extends the needsRelocateWithSymbol by a new
parameter "const MCSymbolData &SD", passes in the target symbol,
and updates all derived implementations.

In particular, in the PowerPC implementation, this patch removes
the FIXME added by the previous checkin.
