fix a memory leak yjasskin pointed out: MCSymbol is bump pointer
...
allocated and thus not freed. This is cool except that it contains
and std::string so the string data didn't get freed. In any case
there is no reason to redundantly store the string data in the
MCSymbol anyway, just make the MCSymbol ref the string data in the
MCContext StringMap.

change EH related stuff (other than EH_LABEL) to use MCSymbol

instead of label ID's. This cleans up and regularizes a bunch
of code and makes way for future progress.
Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places. This is very sad and disturbing. :(
One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction. There should not be any
functionality change from doing this, but I'm not an EH expert.

and passing off ownership to AsmPrinter. Now MachineModuleInfo
creates it and owns it by value. This allows us to use MCSymbols

keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.

MC/Mach-O: Implement initial support for relaxation.
...
- The implementation is currently very brain dead and inefficient, but I have a
clear plan on how to fix it.
- The good news is, it works and correctly assembles 403.gcc (when built with
Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
the resulting binary is exactly equivalent to that when built with the system
assembler. So it probably works! :)
