The tLDR instruction wasn't encoded properly:
...
<MCInst 2251 <MCOperand Reg:70> <MCOperand Reg:66> <MCOperand Imm:0> <MCOperand Reg:0> <MCOperand Imm:14> <MCOperand Reg:0>>
Notice that the "reg" here is 0, which is an invalid register. Put a check in
the code for this to prevent crashing.

Move check of command line options after command line parsing.

The check to not allow -analyze and -disable-output at the same time was done
before parsing the command line flags. Therefore it never triggered, and in case
both options where used opt segfaulted. Fix this by moving this check a after

This test dates from the time when llvm-gcc had problems if two types were
...
named the same, so it had to qualify type names according to the enclosing
scope to ensure uniqueness. This is no longer needed for correctness (though
it may be helpful when reading the IR), so this test has lost its importance.
Zap it because dragonegg will never be able to produce the qualified type name
since modern gcc zaps language specific info (such as whether a type is nested
inside another - needed to get X::Y here) before dragonegg is reached.

Implement the first half of LiveDebugVariables.
...
Scan the MachineFunction for DBG_VALUE instructions, and replace them with a
data structure similar to LiveIntervals. The live range of a DBG_VALUE is
determined by propagating it down the dominator tree until a new DBG_VALUE is
found. When a DBG_VALUE lives in a register, its live range is confined to the
live range of the register's value.
LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially
extended when registers are joined.
The missing half will recreate DBG_VALUE instructions from the intervals when
register allocation is complete.
The pass is disabled by default. It can be enabled with the temporary command
line option -live-debug-variables.
