Ulrich Weigand 716a94f0c9 [DebugInfo] Allow getDebugThreadLocalSymbol to return MCExpr
This allows getDebugThreadLocalSymbol to return a generic MCExpr
instead of just a MCSymbolRefExpr.

This is in preparation for supporting debug info for TLS variables
on PowerPC, where we need to describe the variable location using
a more complex expression than just MCSymbolRefExpr.
