0f301f495b change how we invoke the printer. Instead of passing in the MO directly, 
pass in the MI, operand number, and the type of the operand.

660bc91ec4 This was a good idea, but until this does not break the build of 
lib/Target/Sparc, we should not use it.

8dcbaf2f98 Add initial support for list slices. This currently allows you to do stuff 
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.

c373496a63 Removed the .PRECIOUS of Lex and Yacc output files. 
They are already marked precious in llvm/Makefile.rules, and removing
this line seems to fix the Makefile so that the Yacc output is placed
into the object tree and not the source tree.

74568bc9d4 Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs 
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}
