149cf816bb 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.

3483574772 Change ELFCodeEmitter logic to emit the constant pool and jump tables to
their appropriate sections before the code itself. They need to be emitted
before the function because on some targets (x86 but not x86_64) the later
may reference a JT or CP entry address

23b9f95d35 ELF Code Emitter now uses CurBufferPtr, BufferBegin and BufferEnd, as do JIT and
MachO Writer. This will change with the arrival of ObjectCodeEmitter and
BinaryObject
