require an AddressClass, which is useless at this
point since it already knows the distinction between
32-bit Thumb opcodes and 32-bit ARM opcodes.

keep a shared pointer to their disassembler. This
is important for the LLVM-C disassembler because
it needs to lock its parent in order to disassemble
itself.
This means that every interface that returned a
Disassembler* needs to return a DisassemblerSP, so
that the instructions and any external owners share
the same reference count on the object. I changed
all clients to use this shared pointer, which also
plugged a few leaks.

Fixed the DisassemblerLLVMC disassembler to parse more efficiently instead of parsing opcodes over and over. The InstructionLLVMC class now only reads the opcode in the InstructionLLVMC::Decode function. This can be done very efficiently for ARM and architectures that have fixed opcode sizes. For x64 it still calls the disassembler to get the byte size.
Moved the lldb_private::Instruction::Dump(...) function up into the lldb_private::Instruction class and it now uses the function that gets the mnemonic, operandes and comments so that all disassembly is using the same code.
Added StreamString::FillLastLineToColumn() to allow filling a line up to a column with a character (which is used by the lldb_private::Instruction::Dump(...) function).
Modified the Opcode::GetData() fucntion to "do the right thing" for thumb instructions.

- Addresses with no description were given
comments, leading to useless comments like
"; , "
- Addresses weren't resolved with respect
to the correct module.

them both installed with the LLVM MC version being the default. I renamed the
name of the LLVM MC disassembler plug-in to "llvm-mc" and the LLVM enhanced
disassembly plug-in to "llvm-edis" and they can both be installed for now.
To use the "llvm-edis" disassembler, you can just specify it while disassembling:
(lldb) disassemble --plugin llvm-edis --name main
(lldb) disassemble --plugin llvm-mc --name main
This will allow us to compare the output of the two disassembler and eventually
deprecate the old one when the new one is ready. But it does use the new disassembler
by default so we continue to test it on a daily basis.

Intel disassembler usable.
Also flipped the switch: we are now exclusively
using Disassembler.h instead of
EnhancedDisassembly.h for all disassembly in
LLDB.

which uses the Disassembler.h interface to the LLVM
disassemblers rather than the EnhancedDisassembly.h
interface. Disassembler.h is a better-maintained
API and will be stabler in the long term.
Currently the output from Disassembler.h does not
provide for symbolic disassembly in all the places
that the old disassembler did, so I have gated (and
disabled) the disassembler. It'll be easy to flip
the switch later.
In the meantime, to enable the new disassembler,
uncomment "#define USE_NEW_DISASSEMBLER" in
lldb.cpp.
