Add a parameter to ConstantFoldTerminator() that callers can use to ask it to also clean up the condition of any conditional terminator it folds to be unconditional, if that turns the condition into dead code. This just means it calls RecursivelyDeleteTriviallyDeadInstructions() in strategic spots. It defaults to the old behavior.

I also changed -simplifycfg, -jump-threading and -codegenprepare to use this to produce slightly better code without any extra cleanup passes (AFAICT this was the only place in -simplifycfg where now-dead conditions of replaced terminators weren't being cleaned up). The only other user of this function is -sccp, but I didn't read that thoroughly enough to figure out whether it might be holding pointers to instructions that could be deleted by this.

Change the command 'breakpoint command remove' to 'breakpoint command delete',
to be more consistent with other commands.

load (which can necessarily leave around dead loads).

and set the address as an opcode address or as a callable address. This is
needed in various places in the thread plans to make sure that addresses that
might be found in symbols or runtime might already have extra bits set (ARM/Thumb).
The new functions are:

bool
Address::SetCallableLoadAddress (lldb::addr_t load_addr, Target *target);

bool
Address::SetOpcodeLoadAddress (lldb::addr_t load_addr, Target *target);

SetCallableLoadAddress will initialize a section offset address if it can,
and if so it might possibly set some bits in the address to make the address
callable (bit zero might get set for ARM for Thumb functions).

SetOpcodeLoadAddress will initialize a section offset address using the
specified target and it will strip any special address bits if needed 
depending on the target.

Fixed the ABIMacOSX_arm::GetArgumentValues() function to require arguments
1-4 to be in the needed registers (previously this would incorrectly fallback
to the stack) and return false if unable to get the register values. The
function was also modified to first look for the generic argument registers
and then fall back to finding the registers by name.

Fixed the objective trampoline handler to use the new Address::SetOpcodeLoadAddress
function when needed to avoid address mismatches when trying to complete 
steps into objective C methods. Make similar fixes inside the
AppleThreadPlanStepThroughObjCTrampoline::ShouldStop() function.

Modified ProcessGDBRemote::BuildDynamicRegisterInfo(...) to be able to deal with
the new generic argument registers.

Modified RNBRemote::HandlePacket_qRegisterInfo() to handle the new generic
argument registers on the debugserver side.

Modified DNBArchMachARM::NumSupportedHardwareBreakpoints() to be able to 
detect how many hardware breakpoint registers there are using a darwin sysctl.
Did the same for hardware watchpoints in 
DNBArchMachARM::NumSupportedHardwareWatchpoints().
