3be9c5fbe7 Do not crash when joining two intervals of registers of different 
classes: just ignore that move. Thanks to Vladimir Prus who found the
bug!

520df8464b Fix a bug in the unreachable block elim pass. Dropping all references on a 
basic block clear()'s all of the operands lists, including phis.  This
caused removePredecessor to get confused later.  Because of this, we just
nuke (without prejudice) PHI nodes in unreachable blocks.

a65b4eac3b Revert patches 1.79 and 1.80 which had to do with dead MBB's. Now that they 
don't exist, we don't have to pretend to handle them.

693244fb33 Add a trivially simple pass to delete unreachable blocks from the CFG. This 
pass is required to paper over problems in the code generator (primarily
live variables and its clients) which doesn't really have any well defined
semantics for unreachable code.

The proper solution to this problem is to have instruction selectors not
select blocks that are unreachable.  Until we have a instruction selection
framework available for use, however, we can't expect all instruction
selector writers to do this.  Until then, this pass should be used.

7c77fd50e7 Instead of building a private numbering of MBB's use brg's nifty auto-numbering. 
Also convert df_iterator -> df_ext_iterator for subsequent stuff I'm doing.

d22d9cb800 Do not find these ugly sparc-specific objects by using the annotation API on 
instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!

6f4a596234 Fix a recent regression in Applications/sgefa that Alkis pointed out to me. 
The vector may actually be empty if the register that we are marking as
recently used is not actually allocatable.  This happens for physical registers
that are not allocatable, like the ST(x) registers on X86.
